14694 - Mouseover in page causes whitespace to appear

Status: VERIFIED FIXED

(Core :: Layout, defect, P3)

Description

[Alec Flett]

When I mouse over the first link (Vehicles) on this page, a giant bunch of
whitespace appears (vertically) between the form (with "show only ads with
photos") and the directory, and pushes the whole directory down about 2 inches
on the page.

Looking at it closer, there's no :hover or other stylr rules on the links. It
turns out it's the gfx rendered buttons and combo box. When the mouse moves over
one of them, an incremental reflow command is generated and for some reason that
causes the table to reflow incorrectly

The problem is with the combo box control, which is returning an invalid max
element height.

I'm attaching a small example that demonstrates the problem. Notice the warnings
output to the console when loading

Kevin, the problem is that the combobox code isn't correctly computing the max
element size.
