If you adjust a slider's setting and then click "Undo," the focus on the screen moves from the slider you were working on to the first slider in the set you are working in.

For instance, if I am adjusting a nostril slider that is 50 sliders down from the first slider in the nostril set, when I click "Undo" to change the value of the slider I am working on, the focus on the screen, after I press 'Undo," returns to the 1st slider in the nostril slider set (which, in this example, is 50 sliders away from where I was working).

Note: This same problem also occurs in CC4.

From a productivity standpoint, "Undo" should not move you away from the slider where the value was "Undone."
