Second this. I’d strongly recommend to change this to an option to ‘Update all selected Keyframes’ and keep it OFF by default. I’m still on 5.4 for work so please let me know if this has already been addressed. This is a frustrating feature that I’ve yet to use intentionally, it just causes confusion and undoing when editing values and seeing no updates in my scene. Generally users are not editing keyframes that are not on the active frame in sequencer.
