Tested on IE8 (old!) and the behavior is even more different:
- on quirks mode, IE does not respect the body's overflow:scroll property at
all;
- on strict mode, it does, and creates "scrollable body" (not the
documentElement element). It then behaviors like Opera and Firefox, as far as I
can tell.
