Bug Report

Problematic behavior
While sharing read-only by 3+ persons, switching to read-write share freezes firefox's Tab

Expected behavior/code
I would expect that the 3+ persons would be able to edit the file themselves, and let me also continue editing my https://docs.numerique.gouv.fr/docs/

Steps to Reproduce

1. create a doc on https://docs.numerique.gouv.fr/docs/ with table and file attachment and image (I can privately share my real example)
2. create anonymous read-only link to sharing
3. 2 users or more open my link while I am editing it.
4. I create an anonymous read-write link for sharing.
5. BUG: my tab is frozen
6. I ask the others to stop using my link
7. I reload my tab (twice)
8. I switch for read-only anonymous sharing
9. I can use my tab, others can see my changes in real time.

Environment

• Impress version: I don't know what that means. The document is hosted on https://docs.numerique.gouv.fr/
• Platform: happened on april, 18th, around 10AM paris Time.
• My brower is Firefox Browser 136.0.3 (64bits), nixos-1.0, with extensions https://addons.mozilla.org/fr/firefox/addon/darkreader/ https://addons.mozilla.org/en-US/firefox/addon/toggley/ https://addons.mozilla.org/en-US/firefox/addon/auto-tab-discard/ (the last extension did not touch this tab)

Possible Solution
My partners have decided that we will switch to Microsoft Meeting because of that bug :-(

Additional context/Screenshots
I don't even now if this is reproducible. Please tell me if you want me and my partners to try to reproduce the bug.
