Visually, this does the right thing: the ';' has its height increased,
but the text properties look like this:
face ((:height 1.1) font-lock-comment-delimiter-face :height
1.3310000000000004)
fontified t
rear-nonsticky t
Thatʼs not a valid 'face property, unless Iʼm misreading (info
"(elisp) Special Properties"), plus the ':height 1.331' bit is wrong,
thatʼs (expt 1.1 3), not (expt 1.1 4). Yet it works, the height has
been increased.
Is this a bug in our interpretation of 'face properties?
I can fix the code in `emoji-zoom-increase' to produce something like
((:height 1.4641000000000004) font-lock-comment-delimiter-face)
instead, but first Iʼd like to understand whatʼs going on.
