Brackets/braces of invisible (empty) staves affect alignment

Explanation: Brackets—such as curly brackets to the left of the grand staff—affect alignment with the page edge even when hidden such that there is a notable misalignment of the staff with left-aligned content like footer information and the "lyricist" text field. In other words, MuseScore leaves space for the curly bracket on a page even when it is not visible.

Steps to Reproduce Issue:
1) Create a score with one voice and one piano.
2) Populate the vocal staves on the first page with musical content.
3) Populate the vocal and piano staves on the second pages with musical content.
4) Hide empty staves by selecting Style>Score>"Hide empty staves within systems" and unselect "Don't hide empty staves in first system" (to clear the piano from the first page).

Result: The vocal staves on the first page are not flush with the page margin.

Example: The attached score shows the misalignment. The first page is meant to replicate a hymnal page, which does not typically use square brackets for the voice parts (a space-saving practice, perhaps?), and it shows the misalignment clearly. This issue also impacts songs in which a movement or page of content is unaccompanied.
