[BlackBerry] GUIMark3 page is rendered at a large scale during history navigation back
https://bugs.webkit.org/show_bug.cgi?id=105130
Patch by Jacky Jiang <[email protected]>.
Reviewed by George Staikos.
PR: 265999
During history navigation, UI thread can blit the contents at a bad
view state before WebKit thread restores the view state.
Suspend screen updates before goBackOrForward() and resume thereafter
so that screen can be updated after the correct view state is updated.
No need to render or blit here, as goBackOrForward() can dispatch a
message to WebKit thread to do that in WebPagePrivate::restoreHistoryViewState().
