Log Message:
-----------
Replace history when navigating an initial about:blank subframe
https://bugs.webkit.org/show_bug.cgi?id=324079
rdar://187298226
Reviewed by Rupin Mittal.
Per the HTML navigation spec, history handling must be "replace" when the
target's active document
is still the initial about:blank document.
https://html.spec.whatwg.org/multipage/browsing-the-web.html#navigate
FrameLoader::continueLoadURLIntoChildFrame() already does this for a frame's
initial src load, but
NavigationScheduler otherwise relies on the "onload has not been dispatched
yet" heuristic.
Make NavigationScheduler::mustLockBackForwardList() lock the back/forward list
whenever the target
is a subframe whose document loader is still for the initial about:blank
document, independent of
onload.
