David is correct. The markup is invalid, and so in an attempt to fix it, we are turning: <font><div></div></font> ...into: <font></font><div><font></font></div><font></font> Thus, styles on the inner <font> are overriding those on the <div>, since the style system thinks the <font> is the child of the <div>, and not the other way around. This is occuring because of invalid markup. We have no time to fix this before the 6.0 release, and after 6.0 there will be no point in fixing it since people will have to "code around" 6.0's "bug" in this matter anyway, so at that point whether we change our behaviour or not will not be important. -> WONTFIX.

Verifying WONTFIX.
