Selecting in an iframe can cause main page scrolling https://bugs.webkit.org/show_bug.cgi?id=147431 rdar://problem/19244589 Reviewed by Zalan Bujtas. Source/WebCore: The RenderLayer auatoscroll code walks up the RenderLayer hierarchy, crossing frame boundaries. However, as it crosses into an ancestor frame it failed to map the target rect into the coordinate space of the new frame, which caused us to scroll to an incorrect location in that parent frame. Test: fast/events/autoscroll-in-iframe.html * rendering/RenderLayer.cpp: (WebCore::parentLayerCrossFrame): Make the layer a reference, and pass in an optional rect. When crossing frame boundaries, map the rect from the contents of the child frame to the contents of the parent frame. (WebCore::RenderLayer::enclosingScrollableLayer): Pass optional rect. (WebCore::RenderLayer::scrollRectToVisible): (WebCore::RenderLayer::hasScrollableOrRubberbandableAncestor): * rendering/RenderLayer.h: LayoutTests: Test that uses eventSender to select in an iframe after scrolling the main page. * fast/events/autoscroll-in-iframe-expected.txt: Added. * fast/events/autoscroll-in-iframe.html: Added.
