Drag and drop spec failure - RangeError: Maximum call stack size exceeded

The following error occurs intermittently on CI builds (never locally, it seems):

SUMMARY:
✔ 9166 tests completed
ℹ 5 tests skipped
✖ 1 test failed

FAILED TESTS:
    drag and drop function
      when rearrange is enabled
        when rearrange button is clicked
          ✖ shows a remove button, which removes a panel
            Chrome
          RangeError: Maximum call stack size exceeded

The test in question was quarantined in this MR: !18426 (merged)

This is possibly caused by vue-test-utils being used in karma tests. There is a large discussion about the general problems with this, as well as some solutions: gitlab-foss#56317 (moved)
