Reproduce the regression in a Nightly main build on macOS, using the attached videos as the behavioral reference, and compare it with the latest released version where repeating a note works. Trace the keyboard interaction for r and identify the change that broke it; done means r again repeats the selected note without regressing the released behavior.
