Answer 1

Hello,
Welcome to Microsoft Q&A!

I can reproduced this behavior. this problem will occurs in both of the RichEditBox and TextBox that use ScrollViewer as scroll container. It has the limitation of max content that can be used in the scrollview. And it is by design for keeping the performance of control.
If you want to display the rest of content. the better way is split it over multiple lines.

Thank you.
