Saving Score in Concert view causes transposed Parts to reopen in Concert, causing mismatched key signatures.

1. Create new file with one or more transposing instruments
2. Create parts
3. Save file with "Concert Pitch" selected in score view.
4. Close and reopen saved file
   
5. The Part and Score both have "Concert Pitch" pressed down but the key signature is not transposed in the Part view
6. Transposing is now incorrect. If I deselect the "Concert Pitch" button in the Part view, it re-transposes the key signature.
   
7. The Score's key signature transposition no longer matches the Part
   
8. When exporting parts, the parts are now either Concert (untransposed) notes with a transposed key signature, or correctly transposed notes with the wrong key signature. demo-Bb_Clarinet.pdf demo-Score_and_Parts.pdf

This can be fixed by placing a new key signature in the score, but the issue pops up again when I save and reopen the file. The only workaround is saving the file with the Score in Transposed (not Concert) view.
