495659 - Elements which overflow the right side of the window cause the scrollbar to become non-functional

Status: VERIFIED DUPLICATE of bug 286828

(Camino Graveyard :: General, defect)

Description

[Dan Lidral-Porter]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en; rv:1.8.1.21) Gecko/20090327 Camino/1.6.7 (like Firefox/2.0.0.21pre)
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en; rv:1.8.1.21) Gecko/20090327 Camino/1.6.7 (like Firefox/2.0.0.21pre)

If an element on a webpage overflows the right side of the browser window without creating a horizontal scrollbar (for example, the floating table of contents on the linked page) causes the scrollbar the become unresponsive wherever the element intersects the right side of the browser window–Camino sends the click events to the webpage. Clicking on the lower part of the scrollbar, past the overflowing div, functions normally.

Reproducible: Always

Steps to Reproduce:
1. Create a div that overflows the right side of the screen (or go to the linked website)
2. Click on the scrollbar where the div overflows the right side of the screen.
3. There is no step 3!
Actual Results:  
The click events are sent to the page–right clicking brings up the contextual menu expected when one clicks on a webpage, not the scrollbar.

Expected Results:  
The clicks should be sent to the scrollbar so you can, you know, move it.

I'm using straight Camino 1.6.7, no addons or modifications, and OS X 10.5.7.

Can you reproduce this in Firefox 2?

If so, can you reproduce it in either Firefox 3 or Camino 2.0 beta?

I'll hazard a guess that this is a Core bug that was fixed in Gecko 1.9, but I'm confused. In your description, you say "if an element overflows *without* creating a scrollbar", and then go on to mention clicking on a scrollbar in the steps to reproduce. Where is the scrollbar?

I don't see a floating table of contents on the linked page. Is there some step involved in bringing it up?

I assume it's "without creating a horizontal scrollbar" and the scrollbar in question is the vertical scrollbar. But I scrolled all over that page at various window sizes in 1.6.7 and I could never get the window to be smaller than the content without getting a horizontal scrollbar.

A simple test case would be helpful here.

For some reason, the floating table of contents on that website sometimes shows up and sometimes doesn't. I put up a simple test case on my website: http://dlpart.com/misc/test. Make sure that the text in the grey box on the right overflows the right side, and then try to move the scrollbar by clicking on it where the box overflows.

This is a dupe of and old bug (gecko 1.8.x); need a moment to dig it up.
Works fine with Camino 2 (and Fx 3.x).
