Inheritance mapping works inconsistently

[Paulskit]

Version: x.y.z

Automapper 10.1.1

Expected behavior

Regardless of order, fields should be mapped consistently.

Actual behavior

If derived class goes first, mapping works correctly for this and all further mappings.
If derived class goes after base class, mapping works incorrectly for this array and any other array afterwards (I assume it just caches the incorrect plan).

Steps to reproduce

Here is the Fiddle to reproduce.

Just change works to doesNotWork on line 27 to reproduce the issue. Notice AdditionalProperty value in the output.

Try the MyGet build.

Thanks for the repro. I've added it as a test just in case.

Will try. Thank you!
