Good catch, seems I applied the rule to widely while it should only be for contenteditable=true https://github.com/nextcloud/text/pull/2712/files#diff-e45ce3a454c97498daa53f43c438ba1be6ee1b3cfea83cee90053fbe14ad78b2R17-R18
I have a problem that may be somehow connected: if I share a folder read-only, the .txt and .md files in that folder can't be viewed. The window is empty, with only the filename shown at the top, and in the console I have the following error: PUT https://xxxxxxxxx/index.php/apps/text/session/create 401 (Unauthorized)
