Basically, it looks like IE does strip whitespace in some cases, the main
difference is that it doesn't handle #123 the same as #112233. Since that
would introduce an incompatibility with CSS, and since there was no
interop on that case, I figured (based on input from Aryeh and dbaron) we
might as well go with the sane behaviour.
Interop isn't perfect here so there's not really any winning whatever we do.
