Suggestion
In order for front-ends to be able to implement "Mark as Unread from this message" (like it's possible in Skype), Matrix needs to allow the read marker to go backwards.
My current opinion is we should separate read receipts from notifications instead of allowing them go backwards. For reasons discussed on MSC2867, going backwards is way more complicated.
