But it does. To a location in a different flow. Sometimes but not always. The playhead should remain where it was before/after using the Instrument Filter. Also, preferably, for good usability the playhead line should stay at the same position on the screen after operating the filter.
Activating or deactivating the instrument filter doesn’t move the playhead. If you have a reproducible case that demonstrates this problem, please attach a minimal project here with the steps required to trigger it, and we’ll take a look.
