/* `overflow-y: hidden` keeps a wide formula's horizontal scrollbar from
bringing a vertical one, but it also clips at the padding edge. KaTeX
sizes the block from its own font metrics, and a glyph it has no metrics
for — the CJK label on an mhchem arrow, `->[燃烧]` — draws taller than
the box, so its top was cut off. The padding is that headroom; the margin
gives it back, so the block still sits 1.5em from its neighbours. */
