It is possible to start the M700 Survey Scanner's retract animation while its deploy animation is already playing, resulting in a buggy animation where the scanner snaps open in a single frame

Steps to duplicate:
Build a craft with the M700 Survey Scanner
Add the 'toggle' action to an action group
launch
trigger the action group to deploy the scanner. Then quickly trigger it again while the deployment is still underway
you will see the scanner immediately snap to its fully deployed configuration, then play its retract animation

by analogy with other retractable parts, the correct behaviour should be to complete the deployment animation, and ignore the second action group input
