/* The time column usually just needs enough space to display the
timestamp. The minimum width here is enough for "22:22 PM", which
is roughly the widest this will be in English; this is nice as the
timestamps and message controls will be vertically aligned.
But in some locales, the time encoding is wider, (especially where
the "PM" abbreviation is longer), so we allow the column to be
wider for individual messages if required, up to `max-content`, to
prevent ugly line-wrapping. In practice, it's unlikely we'll see
anything wider than 60px. */
