Edit group content => The Z-value is set to 0!

1. Create a group of radiobuttons

2. Give the group Z-value 10

3. Click on an element inside the group and move it

Now, the Z-value is changed to 0!

Not very helping when arranging elements in different “layers”…

I seems that making a change in any way to any of the embedded elements, the Z-value of the groups changed to 0.
