user not able to delete his/her own comment at reviewing cases tab

[csonuryilmaz]

Description of problem

Documentation says

.. Each user is able to delete only their own comments ..

at here.

But I can't delete my own comment at Reviewing Cases tab which was entered for a test case in a test plan.

Version or commit hash (if applicable)

Version 6.10

Steps to Reproduce

1. Open a regular account at https://public.tenant.kiwitcms.org/
2. Open a test plan. (I've used this one.)
3. If Reviewing Cases tab is empty, create a dummy test case. (I've created this one.)
4. Open comments section of test case.
5. Write a dummy comment.
6. Click on Delete Comment button for newly created comment.
7. Accept confirmation dialog with OK button.

Actual results

Nothing happens on UI.

When inspector is opened to see network requests and their responses, /comments/delete/ POST request gets 302 response and is redirected to location /accounts/login/?next=/comments/delete/.

Expected results

User's own comment should be deleted as defined in documentation. If there is a problem, (for example, insufficient permissions vs.) it should be visible at UI clearly.

Additional info (Python traceback, logs, etc.)

Nope, sorry.
