@ mention in Design comments adds a Todo that can only be cleared from personal Todo list

Summary

When someone mentions you in a comment on the Designs tab, it adds an entry to your personal To-do list. However, the main issues does NOT show the "Mark as Done" button, nor is there a way to mark as done from the Designs tab. The only way to get the todo to clear is by doing it directly from your personal To-do list.

Steps to reproduce

  • Open an issue, add something to the Designs tab
  • Add a comment on the design and @ mention another user
  • Confirm user has an entry for this in their To-do list
  • See that containing issue does not show "Mark as done" for that user when viewing the issue

Example Project

(If possible, please create an example project here on GitLab.com that exhibits the problematic behavior, and link to it here in the bug report)

(If you are using an older version of GitLab, this will also determine whether the bug is fixed in a more recent version)

What is the current bug behavior?

Current behavior is the Issue shows "Add a To Do" button in the Todo section on the right nav

What is the expected correct behavior?

Issue should show "Mark as done" button; clicking will clear the todo item from the Designs tab and remove from the user's To-do list.
