73825 - Layout is inconsistent in how it invalidates views

Status: RESOLVED FIXED

(Core :: Web Painting, defect)

Description

[Kevin McCluskey (gone)]

This bug was broken off from bug 19256

Layout is not consistent in it's invalidation of views. Some frames always
invalidate their bounds when they change size, others rely on the invalidation
comming from the container changing its size (nsTextFrames are in this
category). All of the frames should invalidate their extents when then change
size. The container frame should only invalidate the newly exposed area of the
view when it changes size. 

When this is fixed we must modify nsContainerFrame::SyncFrameViewAfterReflow to
call:
vm->ResizeView(aView, frameSize.width, frameSize.height, PR_TRUE);

instead of: 
vm->ResizeView(aView, frameSize.width, frameSize.height, frameSize.width == width);

This change to SyncFrameViewAfterReflow was performed a while ago.
