If you select font-name type character and press delete font tag will be left. The only good news is that Chrome now drops "Apple-style-span" attribute.

Safari:
<font class="Apple-style-span" face="'comic sans ms', cursive">h</font>

Chrome:
<font face="comic sans ms, cursive">d</font>

Webkit does not add Apple-style-span class any more, although it still transforms span{color} to font tag. But this issue has its ticket #8438 and all Webkit issues with backspace are grouped in #9998.
