To be fair to these editors the disc ID submission user interface is simply awful and nowhere does it display the track times of the disc ID you are about to submit nor does it display the existing track times (if any) of the release you are about to attach it to. The only feedback you get is the total number of tracks.
You can only get a nice display of the disc ID compared with current track times after it is attached to a release, by beginning to enter a “Set Tracklist Duration” edit (for example with one of these bogus disc IDs)
I always double check immediately after disc ID submission (usually by submitting an update track durations edit) because I have personally made disc ID attachment mistakes on multiple occasions. It would be really nice if all that information was displayed before the disc ID is attached…
