I'd rather to leave this as is. Using text-break instead of word-break to break long text at any character boundary will make the code less readable just to avoid horizontal scroll bar.

I thought it might be consistent with the behavior of code suggestion which seems to break at letters as seen in the link above. Usually the issue appears if you have some code line inline in the comment because code lines usually do not contain many white space.

Well.. For consistency, will change as proposed.

State changed as code fixing the issue is committed (60fe3e5f)

State changed as build #3909 is successful
