How to reproduce

slice multiple objects with support (independent support layer height) and draft shield.

Actual results

When slicing multiple objects with supports (using independent support layer height) and per-object draft shields, the draft shield layer height becomes erratic.
I believe this happens due to the different Z heights when the nozzle moves from supports or objects to the draft shield.
This bug seems to be related to #10788.

Expected results

consistent draft shield layer height
