Collabora Version

Hello,

using the Collabora/Libre Version as seen in the attachment we face the issue that we cannot copy-paste any data wether in calc writer or presenter between 2 Documents.
It gives us the Message that the browser has limited access to the clipboard and shortcuts should be used.
But with rightclick as well as with shortcuts the past into the libre/collabora form is not functioning(no changes will be made to the document).

Steps to reproduce:

1. Open any Libre Document.
2. Open a second Libre Document/or local non Libre Document
3. Try to Copy from one to the other

Result:
The fields you want to paste into stay blank.

Expected results:

The Copy and paste between for expample a libre calc sheet and another one should paste the exact same content between the sheets, as well as a copy from an offline source should.


Additional Info:
We tested this behaviour on Windows 10 Enterprise Edition DE and worked with 3 different Browsers(Edge,Firefox,Chrome).
