This fixes a failure in layout/reftests/bugs/467084-1.html, triggered by
the primary patch in bug 1308876, on Android only (or on all platforms
if I add 'html { overflow: hidden }').
I confirmed locally (on Linux) that, without this patch, both
layout/reftests/bugs/467084-1.html with 'html { overflow: hidden }', and
the reftest added here, fail, but that with the patch they both pass.
