39755 - [FIX]combobox returns width of -1 during incremental reflow

Status: VERIFIED FIXED

(Core :: Layout: Form Controls, defect, P2)

Description

[buster]

debug build pulled 5/17 am
with the attached test case, the combobox returns a width of -1 during the 
incremental reflow that occurs when the drop-down arrow is clicked on.  This 
causes layout to do all sorts of bad things.  Eventually, we assert deep in the 
bowels of line layout, and the resulting layout is incorrect.

This might not be a combobox problem, but Rod will know for sure.

bug 24120 has odd behavior when a combobox is in a floating div.  Figuring out 
what is going on with this bug will help solve that one, I think.

Marking P2/M17/major so it gets some attention.  Rod, feel free to prioritize 
this as needed.  It's certainly worth a half hour of initial analysis sooner 
rather than later, to maybe unblock 24120.

Attachment: click on the drop-down arrow to see the problem

The combobox is returning the wrong value and this causes an assert in line 
layout (or block layout) easy fix, very low risk.

Rod, could you look at 24120 and see if that is a dup of this bug.  With your 
fix, do the test cases attached to 24120 work correctly?

Comment 5

Yes, 24120 work fine and does not assert or fail
