File lock with Office Online not working

[robake1]

Describe the bug
When user1 locks a file either with the option in the webgui called Lock file or when its automatically locked when using the function edit locally, user2 can still open the locked document through the webgui and Office online app without any warning that it is locked. If we try the same with a test setup of Nextcloud Office (Collabora) instead it works and Nextcloud Office says the file is locked and only available for read only.

We think this is related to the Office Online app in combination with the temporary files lock app, so we need advise how to solve this ?

To Reproduce
Steps to reproduce the behavior:

1. Login as user1 and lock a office file (.docx etc.)
2. Open the office document as user1 (.docx etc.)
3. Login as user2 and open the office file from step 1 & 2
4. User 2 can edit the file and dont get any message that the office file is locked.

Expected behavior
We expect Office Online app to show a message saying the file is locked and will open only in read-only, this happens if we try with Nextcloud Office (Collabora) instead in the same scenario.
