I think this comes down to feedback between these two lines:
https://searchfox.org/mozilla-central/rev/9d920555ec81f1c9d4b7fa3b08e23eb88efb60e1/toolkit/components/extensions/ext-browser-content.js#256

If the body padding is a fractional pixel, then we round up, which then makes the body of the options browser a pixel larger.  Then we do that again.  And again.  And again...

I suspect bug 1424615 might be related too.

Kris, I think you originally wrote this code, any thoughts?
