Bug: Reassigning Existing Comments Only Works After Page Reload

When trying to assign an already created comment to another user, the assignment does not work reliably.

Current behavior:
Reassigning a comment only works after reloading the page. After successfully reassigning one comment, the page needs to be reloaded again before another comment can be reassigned.

Steps to reproduce:

tested in issue view page and not model page

  1. Open an existing comment.
  2. Try to assign it to another user.
  3. The assignment does not work.
  4. Reload the page.
  5. Reassigning the comment now works.
  6. Try to reassign another comment.
  7. A page reload is required again.

Expected behavior:
Existing comments should be reassignable to another user at any time without requiring a page reload.
