226894 - onMouseOut not invoked when moved off of first line of LI

Status: RESOLVED WORKSFORME

(Core :: DOM: Events, defect)

Description

[Erik Funkenbusch]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6b) Gecko/20031116 Firebird/0.7+

There may be other ways to reproduce this, but this one is what caught my
attention.  The onMouseOut event is not firing when the mouse is moved out of
the first line of an LI that has had it's display style changed.  If you move
the mouse upward or downward out of the block, the event fires.  If you move
past the first line, then move the mouse left or right, it fires.  If you move
the mouse left or right on the first line, it doesn't fire.

Reproducible: Always

Steps to Reproduce:
1. Load a page with the attached HTML/JavaScript

2. Move the mouse pointer over the "Test" element, which will cause another UL
block to be unhidden like a drop-down menu.  

3. Move the mouse downward to the first line that says "Stop Here"

4.  Move the mouse left or right off the edge of the element.  Notice that the
block does not hide.  Move the mouse back, then off again, and the block hides.
 Move the mouse back and then up or down off the element and the block hides.


Actual Results:  
The onMouseOut event does not fire.

Expected Results:  
The onMouseOut even should have fired.

Attachment: HTML for use with the test case

This code provides a suitable environment in which to verify the bug

Correction to the "Steps to reproduce".  Step 3 says the element is 
labeled "Stop Here" but is actually labeled "Test".

This is still broken, at least on XP, and I don't think this is implementation
specific, so it needs to be readdressed.  

To verify, move the mouse over the Test item, then move the mouse down over the
newly revealed test item, then move the mose off to the left or right (making
sure not to move back over the orignal elements at the top).

"still" using what build?

I thought it was pretty obvious that I was referring to 1.0 Final.

If you intend to simply ignore this bug, then please just say that.  
Otherwise, please stop closing it.  This and bug 226895 are essentially the 
same bug.  Between the two of them you can clearly see that there is a problem 
here with the way the onmouseout event works.

This bug seems to be resolved. WFM at least.
