Folder description shows Text Editor/Viewer header on public share

Describe the bug
A folder with a folder description, when viewed from a public share link, shows the Text Editor/Viewer header (show/hide outline, last saved x min ago, Active people).
This can interfere with the first line of the description and brings no benefit.
It seems to be a broken form of the Text Editor/Viewer UI one also sees when opening a Text-File without write-permissions (on a public share or logged in).

To Reproduce
Steps to reproduce the behavior:

1. Create a folder
2. Share the folder using a public link (read-only)
3. Add a folder description to the folder
4. Open the public share link in another browser or an incognito window
5. Observe the folder description and header above

Expected behavior
If the share link is read-only no Text Editor/Viewer header should be shown (like in the files app when the description is not being edited).
If the share link has sufficient permissions, the User should see the usual viewing/editing UI as seen in the Files App when logged in.

Reproduce the issue with a folder description through a read-only public share, then compare it with the Files App in viewing and editing modes. Trace the public-share description entry point and determine why the Text Editor/Viewer header appears; done means read-only shares omit that header while permitted shares retain the expected viewing or editing UI.
