If this is already reported, I didn’t find it. Searching for this kind of bug is pretty hard, though, since it centers around a single character.
Bug: A single “at” inside a paragraph with multiple “at” turns into the nearest mention.
Expected result: Posting a single “at” with a whitespace behind it does not get turned into a mention
Actual Result: The “at” gets turned into the next mention in the paragraph (not seperated by 2 newlines).
@ so this is a single “at”
@sam This is me mentioning Sam
@sam This is me mentioning Sam``` __Bonus Bug:__ it also deletes following X characters (where X is the amount of characters in the mentioned username)
