Text settings reset to style default in header/footer [MU4.0]

Steps to reproduce:

1) Select a text element in the header / footer (e.g. mini-title)

2) Change font, font size, style, or any other setting in the properties window

3) Save and close the score

4) Reopen the score, the text has been reset to the style default.

Workaround: Use vertical frames instead of the native header/footer system.
