164027 - Trying to resize a tree-column of a tree inside a box with overflow:auto freezes the mouse

Status: RESOLVED WORKSFORME

(Core :: XUL, defect)

Description

[ajbu]

Tested on build WinXP, build 2002082109 and Linux RH7.3/CVS
This resizing works with 1.1 alpha, but stopped working in 1.1b, so it broke 
sometime in June / July. 
When placing a tree inside a box(vbox/hbox) with style="overflow:auto" and 
using a tree-splitter between columns, the XUL Window freezes when trying to 
resize a column.
Expected results: resizing a column resizes the column.
Actual results: window freezes, no more mouse input is possible.
Note that when using a splitter without class=tree-splitter, it works, but 
using:
<splitter style="max-width: 0px"/>
also breaks the resize function.
Problem seems to be caused by the combination of overflow:auto and max-width 0.

Test case follows.

Attachment: Testcase

when resizing with the splitter between First Name and Last Name mouse stops
responding inside window. (mouse still moves, but no change in cursor bitmap
and it is impossible to click)
