170629 - Overflow:auto regression

Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

[Gérard Talbot]

A child node with overflow:auto should take 100% of available remaining width of
its parent node.

This is no longer the case with 2002092408 using XP Pro SP1.

A test case is coming.

I forgot to mention to go to the given url, try any of the 3 demos and you'll
see in the content (bottom) div an extra unused area at the right side which I
suspect correspond to the width of a vertical scrollbar.

There is an unused area at the right hand side of the content area div in this
demo.

I'm quite confused. I don't see what the bug is here. Which DIV is the "content
area div"?

Oh, I was using an old build. Now I see the bug.

Could it be possible to insert the keyword "regression" into this bugfile? In a
sense, Robert O'C. and I confirm that this is a regression.

I'm quite sure this regression is recent since I downloaded many nightly builds
in the last 20 days and I just noticed this layout problem today.

The regresssion was caused by my checkin for bug 169610.

I think we should backout the change until I can figure out a better fix.
