Status: RESOLVED FIXED

(Core :: Layout: Form Controls, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021130

If I want to select items in e.g. the Product category select listbox from the
bottom (Webtools) to the top it will not scroll up.

Reproducible: Always

Steps to Reproduce:
1. Click and hold button on bottom item in large select listbox.
2. Drag up to select the entire range of the listbox.

Actual Results:  
It scrolled up to the nearest item which wasn't completely scrolled into view
and stopped there.

Expected Results:  
Continue to scroll up and select items as long as the mouse cursor is above the
top line of the box.

From testing releases I can see this worked in 0.9.8 but not in 0.9.9.

Scrolling down and selecting works though.

The patch for bug 83650 seems to be causing the regression specifically the
changes to nsPresShell.cpp.

This seems to have been fixed now. Can't reproduce in either latest Moz nor
Firebird 0.7 on Linux.
