Invisible flag not saved for individual occurr. of repeatable text.

1) Open any multi-page score.
2) If there is no copyright text, add one.
3) Mark as invisible the page number on page 2 and/or the copyright notice on page 2: the invisible status is followed on screen, on printer, on extracted parts and exported to PDF and similar: so far, so good!
4) Save and re-load the score.
5) The texts are visible again!

Thanks,
