some Snapping functionality seems to be broken?

Is it possible that Snapping lost some of its functionality in recent Updates? Right now I am using 17.1.1 build 9, and I am unable to do the following thing:
I am using the Mouse and hovering with a Clip, that was taken from the Viewer Window (!) right above a populated Timeline. Normally I used to be able to toggle snapping on/off (using a hotkey) while hovering with the Clip around. But now the toggle state is locked and only after releasing the clip into the timeline Ii can change the toggle state with a hotkey.
Maybe it is me doing something wrong? But if not, I am asking to make it possible again to dynamically switch toggle on/off by hotkey while manipulating the timeline.
