Not reproduced directly in the last 90 days. Some builds are failing on that test but for unrelated cause:
All on master, 2026-09-04 to 09-14. A commit for XWIKI-24372 (9c9d9703) broke the minified realtime JavaScript, so editors never joined the realtime session. Every test timed out at its first step waiting for the realtime toolbar to report it was connected, on Firefox and Chrome. Fixed by 07ae6d66.
