Instead of using overflow:hidden on the body to hide the scrollbar, this patch sets scrollbar-width:none on the html element. In some cases overflow:hidden is set on non-root scrollers (i.e. div elements); in those cases it is replaced by overflow:scroll;scrollbar-width:none to get an equivalent effect. One test had a pre-existing visible scrollbar on a nested scrollframe, but which started failing with a small fuzz difference. I left the scrollbar as-is and added an annotation to the reftest.list file. Note that this only updates the tests that use reftest-async-scroll as those were the cases that were easily detectable, and causing problems with the apz.allow_zooming=true pref.
