Disable "Light" automated emojis when they're toggled off.

You can disable turning :D to 😄, but you are powerless to configure some other things

™ does something weird and becomes :tm: instead of just remaining a unicode character? (It seems to have stopped becoming an emoji, but becomes the unicode character, but returns to being :tm: when editing)?

But also, ⚠ becomes ⚠️ and you can't stop it from doing so unless you use code tags or something. Just a minor rough edge inconsistency that I'd find it really cool if they'd fix.  No doubt there are a few others.
