!!TODO copy from figma!!
 Whenever the API lets us know a save fails, show the message !!TODO (including: Try clciicking save again (later), good luck!)!! in an overlay to the user as shown in the mock
 Initially the popup appears on top of the content page (between grey bar and content, if possible, but if not possible, then above the grey bar)
 Users can scroll content "behind" the popup
 The error message does not disappear until the error is resolved (successful save, to the user as shown incancel button or leaving the !!mock!!page)
- In the future we might want to differentiate between errors that might work after trying again.
- Editors would have to try again themselves
- The note itself probably does not need to be "removable", but just disappears with read mode once a save was successful.
