[KeywordAlerts] Breaks custom emojis with keyword in the name

[ShortTimeNoSee]

Describe the bug

If an emoji's name (custom emojis confirmed, haven't tested with built-in emojis) contains a keyword (no regex set, just plain keyword) and the bold-first-instance setting is enabled, the custom emoji will be broken.

To Reproduce

• Enable "Bold the first instance of a keyword in a message"
  
• Have someone send a custom emoji that's name has the plain, non-regex keyword.

Expected behavior

Keep the emoji intact (while keeping the alert and mention (if mention setting is enabled), or ignore the keyword mention entirely (no alert or mention).

Priority

P3 or P4

Additional context

I am aware that the setting does state that "issues may arise" (and that you "do not care" 🥱), but I thought I'd submit this issue anyway.

There are workarounds using regex.

Example:

(?<!<:[\w_]*)(?:Nick)(?![\w_]*:[0-9]+>)
