Bracket color insconsistant between Continuous and Page view

Custom color of brackets isn't the same on Page and Continuous view

Steps to reproduce :
- Open MuseScore
- The default score "Bilder einer Ausstellung" should be there
- In the Page view, set a color (ie. red) for the bracket before the first measure is close to the two staffs
- Change to Continuous View
- The bracket color is black. Change the color to a different one (ie yellow).
- Change back to Page view, the color of the bracket is red.
