        Following r243808 we no longer defocus a <select> on iPad when its popover is dismissed as a
        result of picking a value for it. This is to make the behavior of <select> on iPad like the Mac. 
        However the tests platform/ipad/fast/forms/{select-form-run-twice, unfocus-inside-fixed-hittest}.html
        depend on the old behavior. So, we need to update them to no longer expect a defocusing of the
        <select>/the end of form control interaction.

        since the flakiness was due to the fast clicks everywhere behavior being enabled on iPhone.

        Finally, we can now remove the hack where ui.tap() in the Pointer Events utility returned

        QuotaExceededError on GStreamer ports. On the rest of the ports, QuotaExceededError
        is never thrown and the expectations just check that the right buffered ranges
