My plugin with PostProcessor not working with Live Preview when Obsidian starts

I’m creating my new plugin that integrates multiple mindmaps into an Obsidian note. The idea is inspired by markmap of gera2ld.
The problem is that when I close and open Obsidian again, the code block isn’t shown in the living preview

However, in the reading mode, it’s still ok!

I realize that when I open another note, it works very well

I think the problem is related to the Live Preview mode in Obsidian 0.15.9.
