Editing an exiting comment with a user tagged will clear anything after the space, thus making wrong user tagged

To reproduce:

• create a comment on any commit in Bitbucket
• tag a user by their name
• if the user has First name and last name populated when you case your comment, his name will appear in the view
• if you click on Edit the comment, if the user name was FirstName space Last name, anything after the space will be dropped and wrong user will be tagged.

Temp Workaround: before saving the comment after the edit, remove the user tagged previously to avoid having a wrong user tagged and start typing the correct user again and select him on dropdown prompt
