373467 - Collapsing overflow:scroll div on reflow

Status: RESOLVED FIXED

(Core :: Layout, defect, P2)

Description

[Martijn Wargers (dead)]

Attachment: testcase

See testcase, in current trunk builds, the overflow:scroll div collapses a bit after 500ms.
This regressed between 2006-12-07 and 2006-12-08, so a regression from the reflow branch landing.

Note, IE7 doesn't show a scrollbar at all with the testcase.
Opera9 wraps the scrollbar around the text as tightly as possible.

WFM Mac trunk.

I see this on current linux trunk. 
Deleting the new style rule through the dom inspector doesn't make the div expand again.

I tend to think that either the second layout is correct (and the first wrong) or both are wrong and the scrollbars should be closer to the text.

May be related to 416752. I can't reproduce on Mac so I'll have to get a Windows build going.

Yeah, the patch in bug 416752 fixes this. I think in the first reflow we set the scrollport to the preferred scrollbar height, in the incremental reflow we set it to the minimum scrollbar height.

Marking fixed now that 416752 is checked in
