When editing values of the randomizer slider by clicking on a space the user sometimes has to undo twice. This only happens if the user was in one of the min max number fields and without exiting clicks on a space on the slider

*Repro*
# Create and open an ARC
# Click on a randomizer toggle to enable randomization
# Click on either the min or max number fields on the right of the randomization slider
# *Without exiting(!)* (see recording) click on an empty space on the randomization slider to set a value for one of the sides
# Undo

Expected: The slider value is set to the previous value, e.g. 0

Actual: The slider value remains the same until the user undos again
