Annoying Font Bug

[Richard Heck]

It's taken me a while to figure out how to reproduce this bug. For a 
while, I though it must be me hitting the wrong keys somehow. But now I 
can give a recipe.

Open a footnote. Type a few characters, then hit "emphasize" (Ctrl-E, 
however you like). When you start typing now, the characters will be the 
wrong size. This does not affect LaTeX output, but only the on-screen 
rendering. This happens ONLY when you are at the end of the inset, and 
only if you have not backed up or something. It's most obvious if you 
put a footnote in a section title, for example. Then you get huge, 
sans-serif italics, e.g.

This is in both branch and trunk. Presumably the "old font" or something 
is still set to whatever was outside the inset.
