Full page flush

Version: Joplin 1.0.197 (prod, darwin)
System: Mac os 10.15.3 (19D76)
Bug: when I write a long md document, if I wrote a mermaid graph ,the page will flush, and the page will show the first part of the document. I need to scroll down to the specific part that I work with, which is very inconvinent

Thx
