/* overflow-x deliberately NOT on body (or any ancestor of .topbar/.sidebar/
   .toc) - overflow set to anything but visible on an ancestor silently
   disables position:sticky for every descendant in WebKit-based mobile
   browsers. That was the real cause of a real bug: the mobile hamburger
   button (inside the sticky .topbar) stopped being reachable the moment
   you scrolled away from the very top of the page, since the topbar's
   stickiness was quietly broken. Scoped to .content instead below, which
   is a sibling of the sticky elements, not an ancestor - still contains
   the actual risk (wide tables/code blocks bleeding horizontally) without
   breaking anything sticky. */
