popper upper glass issue

little demo to illustrate the problem with the glass.
To reproduce this you have to already have glass enabled at the start of the table. The ball will have no problems going up and through the habitrail.
Deactivate the glass and reactivate it. Now, suddenly, the ball will collide with the glass.
Reloading the table with glass enabled lets the ball go up, again, without any problems.

This demo will be deleted after the developer reviewed it.
