This displays the file path on its own line and does character-level
wrapping on the path only.
Ideally, we would just apply character wrapping to all words that are
too long for their line. There are CSS props for that but I haven't
been able to find a reliable way to do it without setting a width on the
outer container, which we don't want here (modals stretch based on their content). So this is the best compromise I can come up with.
