inline mindmap resize handle sometimes missing

obsidian:: 1.1.8 obsidian-mindmap-nextgen::1.8.1

i run this plugin, a line at the bottom not display.

Can you add this control method. This eliminates the need for manual adjustment. Of course, both methods would be better together

That's already how it works. The frontmatter setting works like this:

---
markmap:
  height: 400
---

I will fix the case of the vanishing resize handle.
