Display on playback gets confused when text frame added to start
See discussion and sample score at https://musescore.org/en/node/290142.
Create a score that includes hidden staves and multiple systems on the first four pages, a tile frame and save it.
Select the title frame and add a text frame.
Put some text in it
select the new frame and apply a page break
DO NOT SAVE
Notice that at the end of about page 2, the display jumps back to the top of page 2, but plays page 3. The playback cursor will be obviously wrong.
Stop playback and notice that the page that was not displayed is missing.
Save the score and all is as expected, the missing page comes back and playback returns to normal.
