Status: RESOLVED WORKSFORME

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Nick Lowe]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10

Notice the ticker at http://news.bbc.co.uk

When the cursor is placed over the ticker, the colour and cursor change as 
expected. However, when the cursor is moved off, the colour and the cursor 
stick in the changed state. This does not happen in Microsoft Internet 
Explorer, where the colour and cursor change correctly on MouseOut.

Reproducible: Always
Steps to Reproduce:
1. Go to the BBC News website at http://news.bbc.co.uk/
2. Notice the colour of the ticker which scrolls across the screen.
3. Place your mouse cursor over the ticker - notice that the colour and cursor 
icon change. (This is expected)
4. When you move the mouseout, the colour of the ticker text and the cursor 
icon (now in the hand shape) stick. This should not happen.
Actual Results:

Expected Results:  
The same page viewed in Microsoft Internet Explorer works correctly. The 
ticker reverts to its original state - and the cursor goes back to a normal 
mouse from the hand cursor. This is what should happen.

The js ticker is inside an iframe. It updates it's text with the .innerHTML
property. There is a style rule a:hover which sets the text color. So when you
leave the ticker with your mouse, the color should definitely change back.

Attachment: testcase

This testcase does not use an iframe, but it is basically the same.
To see the bug, you must over over the text, the background color becomes
green.
When you move the mouse above, to the browser chrome, sometimes the background
color doesn't change back to white (in 50% of the case).

Hmm, actually the background color doesn't change in almost all cases.

I can see the bug in:

Firefox/0.9.1+

Over to events.  Chances are, blowing away the frames when we SetInnerHTML makes
content states all confused.

This is now WFM in current trunk builds.
If someone can still reopen in the latest nightly build, then please reopen.
