292371 - Documents grow too wide with overflow:auto

Status: VERIFIED FIXED

(Core :: Layout, defect)

Description

[Robert Kaiser]

This is a followup to bug 273392 and a regression of bug 240176

In my Linux build from today, the testcases of 273392 stopped jumping around as
expected after the fix for bug 240176 but now all those testcases are too wide
for the screen and show a vertical scrollbar though it's not needed. The
documents have grown in width by approx. the width of a scrollbar.

This is true for those two simplified testcases:

https://bugzilla.mozilla.org/attachment.cgi?id=168032

as well as for the original page where I saw the other bug happening:
http://www.fynf.at/?vd=3

all of those use overflow:auto along with a padding: 1em; on a div containing
some other blocks.

Probably fixed by the patch in bug 47710

You can see a rather extreme case of what appears to be this bug at
http://www.scarygoround.com/ (the document is far too wide). Getting rid of the
div with class="scroll" makes the problem go away.

Attachment: Reduced SGR testcase.

This might not be exactly the same bug, but it's probably similar (or at least
it regressed at the same time). Here's a reduced testcase from the above URL,
anyway.

You guys know about bug 292370 (esp. bug 292370 comment 10), right?
Any chance this is a dupe?

Could probably be related, but I don't think it's a dupe, those cases look very
different from the HTML/CSS side... even if if might go back to the same pieces
of backend code. roc might know more there...

Sorry for that mistake, I meant a horizantal scrollbar here...
