hunting a bug on scripted custom properties not being saved

[-hh]

I had similar behaviour, connected to that, with the new property inspector.

I set and saved properties in LC 7, reopened the stack in LC.

The LC 7 PI shows the properties, also after reopening.
Up to LC 8-dp9, the properties are there, but NOT displayed in the new PI.

This bug is removed in LC 8-dp10.

So there must have been a bug report ...
