shape keys and animation bug

I reported a bug some time ago about shape keys and animations:

If you have an object ocluding a second object and a shape key animation on the first object makes the second object visible mouse over any sensor is still not seeing the second object.
The only way that I found to make the second object visible for the sensor is manually doing a reinstance of the physics mesh of the animated object.
I think that doing it automatically during the action has more sense than doing it manually.
