Bug ID: 148182
Summary: Scrollable area container is not properly cleared when
page is going into the PageCache
Classification: Unclassified
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Layout and Rendering
Assignee: webkit-unassigned at lists.webkit.org
Reporter: bfulgham at webkit.org
WebKit is crashing when a some pages (those containing PluginViews, but perhaps others) are restored from the PageCache. This is happening because the FrameView holds onto a set of pointers to ScrollableAreas, but those render elements no longer exist when the page is revived from the cache.
To correct this, we must clear out these ScrollableArea pointers when the page goes into the PageCache. When the page is reconstituted from the cache, the layout pass will rebuild the set of ScrollableAreas that were in this container originally.
