Description

14 years ago
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050510 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050510 Firefox/1.0+

When you hover with an outline on elements inside a div then it causes the div
to "jiggle".

But once you encapsulate these elements in a <p> then they sieze to jiggle, so
basically, content that is encapsulated in <p>s will not show this behaviour.

Reproducible: Always

Posted file testcase
This is the testcase which was created by dackz.
So basically we get flicker when overflow to the left/top happens...  Seeing
this on Linux too.

It's annoying but it doesn't cause any real problems so I think we'll pass on
this for now. It will probably go away with the changes that will happen in 1.9

Maybe this is the same as bug 296491, which does show a significant problem. If
so I'll fix it when I fix 296491...

I think this is WFM in my debug build that has the "frame display lists" patch
in it (bug 317375).
