Status: RESOLVED DUPLICATE of bug 22274

If an embed (and some cases images) is sitting in a table cell (with padding
0px) by itself and the vertical-align style of the embed is not set a gap is
rendered below the embed which does not relate to any specified styles (it is an
unnecessary gap).  This bug is showing its face around the web on both images
and object embeds.

Reproducible: Always

Steps to Reproduce:
1. Create a table with one cell with no padding and specify height
2. Place an embed (swf file) in the cell and set it to same height
3. Set the background color to something obvious, like red
4. See that the embed has a gap below it which was not specified

Actual Results:  
You see the gap below the embed which should not be there

Expected Results:  
There is no reason any gap should exist around the embed if not specified

If you adjust the style of the embed to vertical-align: 'bottom' you will see
that the gap below the embed disappears

Attachment: Example flash animation with gap

Here you can see a simple example of how the gap forms below the embed, in this
case a flash animation.
