font: 50px / 50px ahem;
color: green;
max-height: 100px;
writing-mode: vertical-rl;
/* Doing this with a horizontal div and max-width ought to result in the same 100x100 green square,
but font rasterisation may (and in practice does) result in different aliasing artifacts.
Therefore I am using the same writing mode as the test,
to make sure we get identically sharp/fuzzy edges on the same sides.

<p>There should be a <strong>green square</strong> and <strong>no red</strong>.
