Group-based component created off-stage gets always mirrored

Steps to reproduce:
1. Create a Group-based component off-stage
2. Add this component as a child to another off-stage container (may be also a Group)
3. Add the container to the stage after some time (at least in the next frame)

Actual Results:
Component contents gets mirrored

Expected Results:
No mirroring

Workaround (if any):
Enforce invalidateProperties() in the dynamically created component during object construction.

The workaround seems to be quite difficult to discover, so I think, this one is major
