Editor freezes when editing specific mermaid block inside markdown

[4ndv]

Summary

When I edit mermaid sequenceDiagram inside markdown file, and move cursor to specific character, entire editor just becomes unresponsive, and stops handling any inputs

Reproduction Steps

Edit this markdown file (backticks are part of the file):

```mermaid
sequenceDiagram
  Device -->> App: Hello
```

Navigate cursor to the second "-" character and advance to ">"

I expected this to happen:

Editor reacts to that command

Instead, this happened:

Editor stops reacting to any commands
