A possible fix needs careful testing of different ways that the text editor is embedded in scroll containers:

• Single file opened in the viewer as a logged in user
• Open a file on a public share link of that file
• Open a file on a publich share link of a folder
  • Make sure to test this with Talk enabled and disabled as talk registers a sidebar on the public share pages
• Collectives regular page and share links
• Notes
