FWIW, I've seen this and complained in my head about it probably a
million times. I keep putting it off until I have time to sit down and
figure out whether it's us or trac itself, so I haven't done anything
about it -- but yes, it's known, yes, it's annoying, and yes, it
should be fixed. Maybe open a trac ticket saying someone should
determine the cause (us or trac) and fix it/file a more precise bug
report. Okay, I guess I'm not *quite* that lazy:
