Visual indication of pending changesets

[webzwo0i]

It would be helpful if there was some indication that a changeset is still pending and no ACCEPT_COMMIT was received. Otherwise, especially in cases like https://github.com/ether/etherpad-lite/issues/5108 when a reconnect happened, users think their edits are saved, while they are not, they leave the pad and their changes are lost. This is due to the editor immediately rendering the changes and committing the changes in the background. In case they are not accepted, editors handle the error (probably they reconnect).

I'm thinking about the UX. Maybe something like "An edit you made is still pending."
