python extrude, component's sketch goes invisible, then component is out of sync

I'm trying to extrude a profile contained in an included component.
It works OK from the user interface. In an empty design, include the attached file. The single component has a single sketch containing two profiles. Select one or both of the profiles and extrude a 1mm body. The sketch in the included component remains visible. I expected this behavior, sketch visibility for included components should be locked.
If done through the python script below, the extrusion works but the sketch containing the profile goes invisible. The component is then shown as out-of-date, which isn't surprising since it is now different from the reference component. Requesting an update of the out-of-date component makes the out-of-date indication go away, but the sketch remains invisible.
As a work-around, the script can set isVisible to True after the extrude. Try again but check "Restore Visibility" in the command dialog. It's not perfect, since the component now shows as out-of-date. A user of the script would be surprised and confused by this behavior.
