Creating part from voice 2 does not respect key changes

Possibly related to #282512: Time signatures omitted in voice 2 parts when using voice-to-part feature

I have a vocal score that has a soprano divisi in the last several measures, and I tried using the "Parts" feature to extract a "soprano 2" score. The score has several key changes before the soprano staff is split into "voice 1" and "voice 2". When I create a new "soprano 2" part with only voice 2 selected from soprano staff, the key-changes throughout the score are not created in the soprano staff in the new part, the entire staff remains in the original key of the score.

Attached is a small example score I created to illustrate the key change problem when extracting voice 2. Note that the extracted "Sop2" part has the correct notes, just displayed in the wrong key.
