In the attached file if you scrub the animation the driver updates correctly (cube spins) but when you hit play, the cube stands still.

Can confirm, checking...
(note we had #61014 which might be related...)

So this only works (scrubbing) since 0ec6fa782b.

Without diving deeper, I am not sure where the difference (scrubbing vs. playing) stems from [dont think it is ED_update_for_newframe...]
It is probably best if @Sergey has a look?

here is what I get on frame change
