As far as I’m aware the ribbon buttons will never stay highlighted when using the Animation Editor, but the functionality is still active and you can still use them to switch between the Animation Editor’s Move and Rotate functions using the ribbon buttons.
Just to be sure, this behavior had some interesting interactions which depend on Deferred vs Immediate SignalBehavior.
Could you check that it’s working for you with Workspace.SignalBehavior set to either value? (that it didn’t just get fixed because you changed to working in a different place with a different setting for that)
Good in this case means working.
QoL means the Dragger QoL improvements beta feature
I also acidentally found out that changing to Immediate with QoL Improvementswhile the animation editor was open broke it in some way, creating 2 rotation adornments. Using one removes the other and the current one doesn’t work. Reopening studio actually applies the changes from this error.
