Issue Summary

When I mention an account in either a comment or a card description, if I add the mention inside brackets () when I close and reopen the card the mention no longer shows the name of the account I mentioned and instead shows the ID of the account and it isn't highlighted blue if this is my account.

Steps to Reproduce

1. Open a card
2. Mention a board member in brackets e.g. (@username)
3. Close the card
4. Reopen the card

Expected Results

The mention should show the name of the account that's been mentioned

Actual Results

When the card is reopened, the mention shows the @ symbol and then the ID account that's been mentioned.

Workaround

This doesn't happen if the mention is added outside of brackets ().
