User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a5) Gecko/20041017 Firefox/0.9.1+

1. Focus the scrollable div with all the images
2. Scroll to the bottom of that div
3. Now focus one of the links in that div (using right-click for example)

Result -> you'll see some flash in the recent nightlies.

This seems some kind of regression.
I don't see it happening in:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a5) Gecko/20041008
Firefox/0.9.1+ (7:12 am)
But I see it happening in:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a5) Gecko/20041009
Firefox/0.9.1+ (7:33 am)

I'll attach a minimalish testcase.

Worksforme with a gtk1 build.  Is this a Windows widgetry problem?

Attachment: testcase

oveflow:auto <div>'s are not automatically focused anymore when clicking on it.

This testcase is the same as the original, but with tabindex="1" which makes
the <div> focused again by clicking on it.

Hmm, for some reason I get brief flashes of white now, instead of red with
"testcase2", when I try to trigger the bug.

Comment 9

[Boris Zbarsky [:bzbarsky]]

Sounds like the multiple widgets confuse things could well be similar to bug 47742.

Comment 10

[Martijn Wargers (dead)]

This is WORKSFORME in current trunk build.
The last time is saw this bug is in a 2005-01-03 build, but in a 2005-03-02
build, I don't see the bug anymore.
