Make it easier to add tags to cards

Problem: When I want to add tags, I end up overwriting the card's title.

What happens:

1. Click a card
2. Click the tags icon
3. Start typing
4. Card's title is changed.

What I would like it to happen:

1. Click a card
2. Click the tags icon
3. Start typing
4. Tags are filtered based on my input, card title is not changed
5. hitting enter adds the visible tags.
