Channel change contained in staff text is not reflected in connected part

In my workflow in use connected parts a lot. I have a strange behavior with staff text containing channel changes in connected parts.

1) If I enter staff text in the main score and apply a channel change, e.g. changing the violin from normal to pizzicato this is not reflected in the connected part. The staff text itself is present in the connected part, but not the channel change.
2) If I copy the staff text (in main score) and paste it to a different staff or different position on the same staff, then it is reflected correctly in the connected part, including the channel change.
3) If I delete the staff text from example 1) from the main score, the text is not deleted in the connected part
4) If I delete the pasted staff text from example 2) in the main score, it is correctly deleted in the connected part as well

Can anyone reproduce this behavior? BTW, the same behavior applies to staff text containing midi actions as well.
