CTRL+Z kicks user out of selection in curve editor

Say I want to undo a keyframe or adjustment while editing in the curve editor. The result is the selected actor is deselected, although the actor is still selected in the viewport and sequencer, but the curve editor no longer shows the actor’s curves. The fix seems to be completely unselecting the actor and drilling back down to the channels to be edited. Quite the penalty for an Undo. Anyone else experiencing this behavior?

It seems like there is a correlation to using the Misc Filters > Keyed preventing the curves from being displayed.
