WOPI / Office collaboration with one view-only collaborator

[wkloucek]

Describe the bug

OnlyOffice and Collabora differ in their behavior when it comes to collaboration sessions with one view-only collaborator

Steps to reproduce

Steps to reproduce the behavior:

1. Create a document
2. share it with another user with read only permissions
3. open the document as sharee
4. open the document as share receiver

Expected behavior

When the sharee edits the document, the share receiver will see the changes in real time.

Actual behavior

This is only valid for Collabora. In OnlyOffice the share receiver will not see any changes, even with a reload.

Setup

oCIS with WOPI deployment example.

Additional context

Maybe this is not implemented by OnlyOffice - we need to check. Maybe we need

@tbsbdr @hodyroff This would be interesting to discuss with OnlyOffice.

Is our expected behavior correct? Collabora handles it differently.

Product Question.

Maybe this is dependent on the UserCanAttend property from the CheckFileInfo response?? https://learn.microsoft.com/en-us/microsoft-365/cloud-storage-partner-program/rest/files/checkfileinfo/checkfileinfo-response#usercanattend
