Allow user to choose whether or not hide brackets which span to a single staff when empty staves are hidden
Open the score and tick "Hide empty staves".
On the second page, there's two woodwinds, one brass and one pitched percussion. The woodwinds have their bracket, while the brass and the percussion doesn't.
I consider this "critical" because there's no workaround, and it violates the principle of orchestral music notation.
This problem is very similar to #290409: Stave brackets disappear on a 1 line percussion staff but has no relation to it, as all staves shown here are not 1-line.
