Bug 50119 – RenderObject::minimumPreferredLogicalWidth() sometimes reports wrong value

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Aaron Boodman]

I noticed a change in the behavior of RenderObject::minimumPreferredLogicalWidth() for the root renderer recently, and tracked it to this change:

http://trac.webkit.org/changeset/70546/trunk/WebCore/rendering/RenderBox.cpp

Also see http://code.google.com/p/chromium/issues/detail?id=61370 for the Chromium bug where this was noticed.

It looks to me like a style can sometimes be applied to a body element before it is appended to the tree. In this case, the dirty bit for minimumPreferredLogicalWidth will not be propagated up the tree.

I have a patch that appears to fix the problem, but I would like feedback on:

a) Whether this is a good way to fix it, and
b) How to create a test case

Patch to follow.
