Additional context
Again, not sure if this is a bug but its wobbles my 👀 . I do not see the front matter yaml area even highlighted when the 'Front Matter' extension is disabled. Which lead me to think it was something with the 'Front Matter' extension. But happy to help track it down. Oh, I also have a vim plugin active in that video, but this also happens without vim. Just after each keypress that area flickers.

This blinking doesn't occur when just navigating the markdown file in hugo.
