I want to change track 9 recording from current https://musicbrainz.org/recording/3c49d765-283f-424c-be2d-83fbe7098048 to https://musicbrainz.org/recording/c1120da9-e825-4675-9ebd-9b50fd3e510c
I use Vivaldi but also tried Firefox, and I cannot do it: it does not take my change of track-recording assign in Recordings tab into account (You haven’t made any changes!).
As soon as I leave Recordings tab, the former recording radio button is checked back again.

FTR, the edit note would have been « 3 parts AFTERMATH (3:54), AFTERMATH Ⅱ (3:19) and AFTERMATH Ⅲ (4:52) from Edit #14524147 - Add medium don’t match others at all.
Neither AFTERMATH (complete 5:25) nor 5 parts AFTERMATH (equivalent 5:27 total). »
