There's a pretty good chance this is a duplicate of a bug in the block code
that's currently owned by alexsavulov, I think.

...bug 107873.

Comment 5

[Boris Zbarsky [:bzbarsky]]

confirming since there is definitely a problem.  This should be retested once 
bug 107873 is fixed.

[Alexandru Savulov]

I claim that (like bug 107873) the underlying bug is probably still present, but
this testcase just doesn't happen to trigger the same system.  I don't see
exactly how right now, though.

Please don't resolve this bug without figuring what checkin fixed it and
explaining why that checking is really the correct fix.

Well, the behavior on the testcase changed between 2002-05-10-07 and
2002-05-10-21.  The only layout-related checkin in there is waterson's reflow
tree landing....  Reading over his changes to nsComboboxControlFrame it looks
like it's now less likely to bail out without properly reflowing its kids,
maybe... maybe.  The code is not exactly very readable.  :(

Does http://www.maubi.net/~waterson/mozilla/journals/2002-05.html shed any light?
