Wrong octave in note entry after a line break

MuseScore 1d54c0aec2

1. Create a new score with piano as instrument
2. Insert a system break after first measure
3. Input a whole note by keyboard into the treble clef system that is clearly above or below the stave (for example C or c''')
4. Proceed with the input → the following note jumps to the stave area (which then is the wrong octave)
5. The behaviour is the same with the bass clef system
