[Issue] can't recover some keyframes with undo when they were overlapping

[Cub0use]

Simply dragging or making the keyframes closer to each other by holding ctrl while dragging towards 0 in the timeline works normally, except for the fact that when you undo it, the keyframes deleted during the process (because they overlapped) will not be recovered. Only the ones that were remaining will take back their place.

Maybe all the keyframes are actually recovered, but not repositioned correctly on undo? It seemed a bit wonky, but the issues seem to stem from overlapping keyframes, even when it's not towards 0 in the timeline, as you can see in the video at 6s.
