If a CSS declaration is specified for background-position values in a new mail message, Thunderbird 1.5.0.8/Mac (cross-platform likely but unconfirmed) changes those into two separate nonstandard values that will not work in a non-Gecko mail client.

Steps to reproduce:
1. Open a new mail message window
2. Focus the body text pane
3. Select Format/Page Colors and Background...
4. Click Advanced Edit...
5. Click Inline Style
6. Enter property "background-position" and value "top left" and click OK
7. Click Advanced Edit... and Inline Style again

Expected results
We should see the CSS declaration we entered; that is, background position:top left;

Actual results
Thunderbird has transformed our declaration into -x-background-x-position:top and -y-background-y-position:left. While Gecko will pay attention to these, a non-Gecko e-mail client will not do anything with them and so the style will not be seen.

Other CSS declarations, if entered, retain their standard CSS property names.
This happens in Win XP Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a2pre) Gecko/20061220 Thunderbird/3.0a1 ID:2006122003, add has been a condition in the code for a very long time.
Additionally, this is not the only attribute that get "Mozified"

After further testing, I think that this bug will be marked invalid.
The property names that I see in the advanced edit window seem to be iterim names that just appear while in the composition window.
When I save the composition and then view source the correct property names are there in this particular testcase.
<body
 style="background-repeat: no-repeat; background-position: left top;"
Try saving or sending the message to yourself , then view the source.
Depends on: 258080
These should no longer be shown now that bug 258080 has landed.

That said, there may still be problems with margin-left, padding-left, margin-right, and padding-right.

Depending on what the advanced edit window does, bug 376075 may have fixed those.
