This is actually a really non-breaking, minor issue, but just for the sake of being documented.
So, if you don't have favorite tags, you'll be represented with "Add a favorite tag" link. This link does a similar thing to what "edit" link does: presenting a textbox to input a tag. Except, it doesn't hide "edit" link... which I then clicked out of curiosity, and voila!
Steps to reproduce:
- (prerequisite) Remove all favorite tags
- Click "Add a favorite tag"
- Input a tag and click "Add" (now there is one tag which can be removed by clicking the icon, don't remove it though)
- Click "edit"
- Now you have 2 icons
Exiting the edit-mode solves this bug though, since you cannot access "Add a favorite tag" again. (Same thing happens with ignored tags)
