Agreed that it's curious about resubmitting, but then it is a bug in
IE it's not *that* curious.  It would be far more curious if we'd

I found some other references to the same problem, which appears to be
to do with content encoding, e.g.

I also found this, which finally reminded me why this issue rang a
bell with me; the fix here is what I used many moons ago:
