example of the bug

If you use a web font loaded with @font-face, and have a span of text rendered
without anti-aliasing (for instance, Monaco 9px), followed by text rendered
using the remote font, the text rendered in the remote font will also lack
anti-aliasing. The text will continue to lack anti-aliasing until you use a
local font again, that is anti-aliased. This bug occurs with several different
web fonts that I tested, and several different local fonts at sizes small
enough to disable anti-aliasing, and several different local fonts at larger
sizes that caused anti-aliasing to be restored.

This bug is present in the wild, for example on
http://www.zeldman.com/superfriends/guide/ , assuming you have your fixed-width
font set to a small enough size (I have mine set to monaco 9px).

I've attached an example that demonstrates the problem, with several different
variations of the problem showing up.
