Staff text: copy and paste does not maintain the correct voice
OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 18.104.22.1681459983, revision: 465e7b6
Open the attached file. Select the "p" (staff text) on the first note of voice 2. Copy and paste it to the first available free note in voice 2.
Expected result: The staff text should retain the correct voice: in this case, voice 2.
Actual result: The text changes to voice 1.
Perhaps this also sheds light on #303450: [Musicxml Export] - Text in voice 2 not correctly placed?
