Fix(frontend/comments): Change word-break on comments to break-word

[lol768]

Before:

Problems: Hard to read, no dashes to indicate that words have been broken across lines.

After:

Much easier to read, container overflows in the X direction for super long unbreakable words, which I think is preferable to the original behaviour.
