Research direction

Reproduce the issue in the Normal Modes simulation by opening the One Dimension Screen, optionally increasing the Number of Masses, and collapsing the Normal Modes Spectrum accordion box. Trace the accordion's rendering and update behavior; done means no frequency-value remnants remain visible after collapse in Safari.
