Focus lost on issue view text areas while typing comment in an issue from kanban board

Issue Summary

Focus lost on issue view text areas while typing comment within an issue when navigated from kanban board. 

Steps to Reproduce

1.  Log in to your instance and access the board from two separate accounts in two separate browser windows, your own and any other user's. When you’re an admin you can log in as another user via the admin UI. Pick any non-admin user 
2. Create a new issue on this board and make sure it is visible. Open the issue view for this issue in one of the browser windows.
3. In the other browser window, move the newly created issue to a different column
4. Quickly jump back to the other browser and begin spamming the keys “awd” in a comment text area
5. Eventually, a real-time update will be triggered and focus will be lost on the text area, meaning any subsequent keypresses are registered as keyboard shortcuts (e.g. a opens the assignee field). This could take up to 10 seconds to occur.

Expected Results

Focus should not be lost and users should be able to type without any issue. 

Actual Results

Focus is being lost while typing in the issue comment section.
