Attached is a testcase where individual cells in a table (static and through
DOM) have background-color set to green.  To create the dynamic table, hit the
insert rows button a couple of times to generate a dynamic table.  Also each
cell has a onmouseover event defined which sets the background-color to blue. 
In both the dynamically and staticly created tables, the background-color does
not change to blue when the mouse goes over the cell.  Also when I try to change
the background-color on the whole row, the cell with the initial set
background-color does not change (there is a documented line in the testcase to
uncomment to verify this part).

Everything does work fine when background-color is not initially defined for a
given cell.  If I set the background-color of the entire row, and then modify
the background-color of a cell that works also.

If I put the rows inside <tbody> in the table for static or dynamic case, it
does not makes a difference either.  Testcase actually has the rows inside
<tbody>, but it should work even without <tbody>.


Reproducible: Always

Steps to Reproduce:
See Above


Actual Results:  
See Above


Expected Results:  
Mozilla should be able to modify the background-color of a cell in a table which
already has a background-color set initially.

Attachment: why bother with all the JS?

setting .bgColor does not change the inline style.  Inline style rules take
precedence over all non-CSS presentational hints (like the bgcolor attribute).

This bug is invalid.
