289730 - [FIXr]select dropdown menus missing some options

Status: RESOLVED FIXED

(Core :: Layout: Form Controls, defect, P1)

Description

[Andrew Schultz]

With linux trunk build 20050409, I don't see all the appropriate options listed
in the select dropdown menu for Component when changing a bug report's product.

This regressed between linux trunk builds 2005040605 and 2005040703.  Backing
out the patch from bug 289311 made the problem go away.

I'll attach a testcase, but you can't see the bug unless you pause the input
stream while it's loading.  The document.body.offsetHeight trick doesn't work. 
To see the bug, I had to have a php script deliver the testcase and pause for at
least 0.3 seconds periodically during load.

loading this with linux trunk 20050409, I usually only see 4 and 5 or 1, 4 and
5.

Could bug 289589 be related?

Reliable testcase at http://landfill.mozilla.org/ryl/testSelect1.cgi

I think the comments in the patch sum up what's going on.  I made sure that
this doesn't regress bug 282607 or bug 283117.

This should be reasonably safe and fixes rendering of <select>s when the server
is being slow...
