Merge options are available without permissions

Description of the problem

MR page offers options to merge when I have no permission on given repository.

Which Group/Project (with full path) is experiencing the issue?

https://gitlab.com/inkscape/inkscape/

Approximate date/time when the error occurred.

7 Jan 2020, but I saw it earlier

Describe what you were doing right before the issue occurred.

Steps to reproduce:

  1. Create MR of branch feature
  2. Go to MR page
  3. Do changes to local branch feature and push changes to gitlab
  4. MR page now offers merge options, see screenshot
  5. Reload page. Offered options are gone.

MR: inkscape/inkscape!1263 (merged)

MR page with escalated(?) permissions:

MR page after reload:

I think it's only web page problem, although I didn't test those buttons to avoid accidental merge.
