The second secondary bracket is not needed if it matches the first one

[Dima-S-Jr]

Issue type

Engraving bug (incorrect score rendering)

Bug description

A secondary bracket superimposed on the same one takes place only when a group of homogeneous instruments is divided into subcategories. In systems where one instrument from each category is represented, there should be one secondary bracket. Currently, MuseScore Studio ignores this rule and doubles the secondary brackets in those systems where the instrument categories are not subdivided.
