183472 - td whitespace doesn't trigger hover or mouseover for cell children or parent elements.

Status: RESOLVED WORKSFORME

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

Description

[Ian Sollars]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.2.1) Gecko/20021130
Build Identifier: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.2.1) Gecko/20021130

The CSS ":hover" dynamic pseudo-class is not applied to child elements of table
cells unless you move the mouse over the child element text or cell text.

The JavaScript event "onmouseover" can only be fired in the same manner.

Ex.: Using CSS to display an "a" link element as a block ("a{display:block;}")
within a table cell should cause the ":hover" style for that element to be
applied whenever the mouse is moved over the link element whitespace. The
"onmouseover" event should also fire when the mouse is moved over the link
element whitespace.

Instead, the mouse must be moved over the link text for the ":hover" style to be
applied, or for the "onmouseover" event to be fired.

The border for the link element includes the whitespace that should also trigger
the application  of the ":hover" style and fire the "onmouseover" event.

:hover styles applied to parent elements, or "onmouseover" events tried to
parent elements are not applied or triggered in the same manner.


Reproducible: Always

Steps to Reproduce:
1. Load attached HTML file in Mozilla 1.2.1 (my build is 20021130)
2. Move the mouse cursor over the whitespace in the cells of the two tables
under the heading "Unexpected behaviour".


Actual Results:  
The "onmouseover" event is not fired and the ":hover" pseudo-class is not applied.

Expected Results:  
Fired the "onmouseover" event and applied the ":hover" pseudo-class.

(Just about to upload the HTML file)

worksforme, linux trunk build 2002-12-04-05.  This was probably fixed by the big
events rewrite that landed after 1.2 branched...

Marking worksforme based on above comments and my own testing.  If this doesn't
work for you in 1.3alpha or later, please reopen the bug with a more detailed
