Repeat the steps as follows:
Open “Show Titles in Scrivenings”
First, prepare sections larger than 30.
Each Section has more than 100 rows. (You can also copy 30 copies of the same document.)
Every Section defaults to Title, don’t write Title.
Then, Use the Scrivenings mode and the document is locked in Place
Select the last Section in the Binder, such as Section 25.
It’s going to Section 25.
Click the Section near the bottom of the screen, and the entire Scrivening moves up, sometimes without the cursor. (Because the cursor moves out of sight at the top of the screen)
Repeat, but turn off “Show Titles in Scrivenings” and everything is fine.
I guess, is it possible that the calculation of the Title line height is wrong?
