Ignore history items added by JS without user interaction when navigation back/forward via the WKWebView API
https://bugs.webkit.org/show_bug.cgi?id=241885
<rdar://94838657>
Reviewed by Geoffrey Garen.
Ignore history items added by JS without user interaction when navigation
back/forward via the WKWebView API. This is a behavior similar to the
intervention made in Chrome (https://bugs.chromium.org/p/chromium/issues/detail?id=907167)
to prevent websites from hijacking the back/forward list.
When an history item is added by JS via history.pushState() and without a user
gesture, we now set a flag on that HistoryItem to remember this. Later on, when
calling [WKWebView goBack] or [WKWebView goForward], we will skip the history
item that have this flag set. This behavior occurs behind a linked-on-after
check to reduce the compatibility risk.
Also, navigations via other means (e.g. via JavaScript) are not impacted and will
ignore this new flag.
