Investigate webkit E2E failure

[corneliusroemer]

It looks like a new webkit version released in the past 5 days or so since we last ran tests causes our tests to fail. It's unlikely that the backend patch release causes webkit to fail across the board in CI:

30 failed
    [webkit] › pages/index.spec.ts:4:5 › The landing page › contains an organism ───────────────────
    [webkit] › pages/logout/index.spec.ts:4:5 › The user page › should have usable logout button ───
...
    [webkit] › pages/user/index.spec.ts:6:5 › The user page › should see the groups the user is member of, create a submitting group and leave it afterwards 
  2 flaky
    [chromium] › pages/review/index.spec.ts:53:5 › The review page › approve restricted sequences ──
    [firefox] › pages/review/index.spec.ts:53:5 › The review page › approve restricted sequences ───
  7 did not run
  81 passed (6.4m)

Given that we're not seeing failures now I guess this is fixed
