293110 - "Tree in a box" column drag offsets few columns left to mouse cursor when scrolled to extreme right.

Status: RESOLVED INCOMPLETE

(Core :: XUL, defect)

Description

[jooaun.saw]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

I have a tree with many columns. I can't fit the tree in one screen, so I placed
it in a box to have a horizontal scrollbar. I noticed that the column dragging
doesn't work properly when I scroll to the extreme right. When the column is
dragged, there's a vertical line in between columns to show the new position of
the column. The vertical line is somehow always few columns left to the mouse
cursor.

Reproducible: Always

Steps to Reproduce:
1. Create an XUL box element with minwidth and minheight.
2. Create a tree with enableColumnDrag="true" as a child element of the box.
3. Add several columns to the tree, until the tree width greater than the box
width. (Make tree width at least 2 times greater than the box width to have
obvious result)
4. The box element should have created horizontal scroll bar automatically, so
scroll to extreme right.
5. Try to reposition the columns by dragging them.

Actual Results:  
Vertical line showing new position of column always few columns left to mouse
cursor, thus making column repositioning difficult.
