26466 - file:/// browser uses too big scrollbar-thumb; hard to use

Status: VERIFIED DUPLICATE of bug 24969

(Core :: XUL, defect, P3)

Description

[e75644]

In about 40 lines tall listing setting the browser to 5 lines tall the thumb 
takes up half of the scroll-space. On longer listings it becomes impossible to 
adjust the lines shown on the screen.

It's not quite impossible, but almost. The scrollbar slider has never been the 
correct length, but dragging the mouse *will* let you scroll, if you want to
try to do it with no feedback, and jerky/lagging scrolling movement. This has 
been the same in every build I've tried over the last two months.

I'm not getting any clear picture of who owns this directory-tree stuff from
looking for file:// in the Summary and URL fields in the bug database.

Checking this carefully, it looks like the scrollbar appears for just a moment
sized appropriately for the proportion of the directory listing that is 
visible, but then redisplays in the old, unuseful way of the slider taking up 
most of the scrollbar regardless of anything. Clicking above and below the
slider scrolls the view by "page" and moves the too-big slider in a way that
otherwise mirrors the movement of the view.

This looks like a regression of bug 18193, "[Tree]gfx scrollbar thumb does not 
resize correctly in tree view", FIXED only a few days ago.

Tested with: 2000-02-03-10-M14 nightly binary on Windows NT 4.0
