Dynamic line text does not mask barline on added staves

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

1. Add 2 extra staves to an instrument such as clarinet
2. Add a "cresc..." line to each stave, and position them so the text crosses a barline

Expected: a bit of each barline is hidden where the text crosses in each stave

Actual: this does not happen for the bottom stave

Additional context

A user on Discord experienced a very similar issue with a line text feature not breaking barlines between the first and second stave in a 3-stave piano part, which implies that my repro case is too narrow.
