Regression: most changes don't get pushed to other clients after update to NC 29.0.5

[LostinSpacetime]

My installation: NC 29.0.5 CP 0.7.0 Deck 1.13.1

self-test output:

✓ redis is configured ✓ push server is receiving redis messages ✓ push server can load mount info from database ✓ push server can connect to the Nextcloud server ✓ push server is a trusted proxy ✓ push server is running the same version as the app

After a recent update (maybe NC 29.0.5) new comments on a Deck card are not being updated on other clients. To trigger the update, one (editor or any other client) have to reload the page or simply change the browser-tab and back. This behavior is consistent with different browsers (Firefox and Chromium) and OSs (Fedora 40 and Windows 11) 100% reproducible.
