Describe your issue

I have these settings enabled, but I get this result:

I expect this result (everything is bold except for the parentheses):

(b1az3rs) b1az3rs (@b1az3rs) @b1az3rs

It seems like a bug, although I'm not sure.

I suggest bolding usernames regardless of the symbols around. This is useful when events with several participants take place: people create commands for bots and write a list of participants in the parentheses using @. Currently, some nicknames will be non-clickable in such cases (the first one and the last one).
