        WebDriver: pressed virtual keys not correctly handled in action sequences
        https://bugs.webkit.org/show_bug.cgi?id=205997

        Reviewed by Brian Burg.

        We are assuming that only one virtual key can be pressed and that a key up always releases the pressed virtual
        key if any. We should keep a list of pressed keys and remove them from the list when key up happens for them.

        [GLIB] WebDriver: race condition when session starts
        https://bugs.webkit.org/show_bug.cgi?id=194086

        Reviewed by Philippe Normand.

        This is causing flakiness in the bots, I can only reproduce it locally when my CPUs are at 100%. The thing
        is that sometimes we receive an empty target list right after the connection is established because
        RemoteInspector::setClient() calls pushListingsSoon() before a target has been registered. Most of the times the
        target is registered before the listing is pushed, but it can happen that when pushed, the listing is still
        empty. After the target is registered an empty target list means the connection was lost, so we clear the
        connection and target. We need to ensure we do that only after the target has been registered.

        This happens when the dbus connection is closed right before the response to SendMessageToBackend message is

        signal is emitted. Then, the close commands try to handle the error checking if SessionHost::isConnected(), but
        it still returns true, because the browser is still alive, but the dbus connection has been closed.

        This is currently happening in the GTK+ debug bot. There's a test that makes the browser crash due to an assert,
        hanging the whole process and preventing the rest of the tests from running. When the browser crashes, we
        correctly handle the pending requests, by completing them with an error. However, if the client tries to send
        another command we fail to send the message to the browser and the reply is never sent to the client. In the

        The problem is that we are considering a failure when the browser name doesn't match the capabilities, instead

        The rules to execute a function body are as follows. The algorithm will return success with the JSON

        JavaScript exception being thrown or at any point during its execution an unhandled user prompt appears.

        If at any point during the algorithm a user prompt appears, the user prompt handler must be invoked. If its
        return value is an error, it must immediately return with that error and abort all subsequent substeps of this
        algorithm.

        This will be covered by new WPT tests that will be available after the next upgrade.

        I misunderstood the spec when I implemented this, so we either return a "value" key with the result in case of

        There's no need to include Vector.h when Forward.h will suffice. All we need is to move the template default parameters from Vector, and then the forward declaration can be used in so many new places: if a header only takes Vector by reference, rvalue reference, pointer, returns any of these, or has them as members then the header doesn't need to see the definition because the declaration will suffice.

        WebDriver: ensure we close all windows handles when closing the session
        https://bugs.webkit.org/show_bug.cgi?id=176508

        Reviewed by Brian Burg.

        The spec says that when closing the session all top level browsing contexts should be closed. We are currently
        checking if we have an active top level browsing context and then we try to close it before trying with the
        rest. It can happen that we are in an inconsistent state, for example if the current top level browsing context
        has been closed by JavaScript or another action and the user didn't switch to another one before closing the
        session. In such case, closing the session will fail with NoSuchwindow and any other window open will not be
        closed. It's safer to always ask for all window handles and close them, which is what the spec says too.

        WebDriver: handle click events on option elements
        https://bugs.webkit.org/show_bug.cgi?id=174710
        <rdar://problem/33459305>

        Reviewed by Brian Burg.

        Option elements are considered as a special case by the specification. When clicking an option element, we
        should get its container and use it when scrolling into view and calculating in-view center point instead of the
        option element itself. Then, we should not emulate a click, but change the selected status of the option element
        like if it were done by a user action, firing the corresponding events. Now we check whether the element is an
        option to call selectOptionElement() or performMouseInteraction().

        This fixes more than 20 selenium tests.

        WebDriver: wait until navigation is complete before running new commands and after a click
        https://bugs.webkit.org/show_bug.cgi?id=174670

        Reviewed by Brian Burg.

        We are already waiting for navigation to complete after navigation commands (go, back, forward, refresh), but
        the spec says we should always wait before executing a new command and also after a click. This is causing test
        testShouldBeAbleToNavigateBackInTheBrowserHistoryInPresenceOfIframes to sometimes fail, because it does .click()
        + .title and expects the title to tbe the one of the page loaded by the click. Since the load happens very fast,
        the test usually passes, but in a real case with a slower load, the title of the previous page will be returned
        most of the times.

        Reviewed by Brian Burg.

        When I switched to use std::optional instead of empty strings for the browsing contexts in WebDriver, I forgot
        that automation uses empty string for frames to refer to the main frame. We should handle that case, because we
        are currently considering empty strings as valid browsing context. It's not a big deal because Automation
        converts back the empty string received to the main frame, though. We should also ensure we close the current
        browsing context when switching to a new top level browsing context. This patch adds to helper private methods
        to switch browsing contexts that deal with the special cases.
