User mentions not working for usernames ending in `_`
What does this MR do?
In !45922 (merged) we were a little over ambitious in converting all escapable punctuation characters, including _
and *
.
As a result, @user\_
, which is a valid user format (so that the _
isn't considered an italics character), was no longer recognized as a valid user reference.
So now we're limiting ourselves to just the characters that trigger one of our special references: @ # ! $ & ~ % ^
Screenshots (strongly suggested)
Testing
You can test this by enabled in the feature flag honor_escaped_markdown
. Then you enter the user name @mpeychet
. It should autocomplete to @mpeychet\_
. This should end up being a valid user reference.
However \@mpeychet\_
is NOT a valid reference, because the @
is escaped.
