Read-only documents should not attempt to save

Bug description
I have the text file in the read-only directory on the external storage. In the Nextcloud UI in the browser I can't rename the file, but I can edit it.. And the changes are saved.
Steps to reproduce
- Add the external storage with a read-only directory and a text file in the directory.
- Click on the file in the browser in the Nextcloud UI, change something and close editor.
- Open the file again. The changes should be there.
Expected behavior
I expect the UI editor not to allow changing read only files.

Additional info
The Versions app is disabled.
I don't observe the changes neither in /mnt/ncdata/ nor in external storage. I guess the changes are saved somewhere in the database.

The only place I know of where we may store a changes like this is in the Text editor app session. So I'm moving this over there since this seems likely to be limited to the editor.
I could reproduce this but only if the read only permission was set on the underlying file system, with setting read only in the external storage config it works as expected.
I'm currently unsure what the expected behaviour is for the external storage app and if it actually is designed to respect different file permissions there.
Might be a server bug as the files app also shows file create options even if the folder is read only
