Highlighting stops when rumdl (plugin) does format on save on CTRL+S.

• The Plugin is up to date
• Obsidian is up to date

Describe the bug

[!NOTE]
I don't know if this is a bug in obsidian-shiki-plugin or Obsidian. It's likely not in obsidian-rumdl?

Just wanted to create an issue with info about it, and hopefully someone can figure out where and why it happens.

I use rumdl for linting and format on save:

• https://github.com/rvben/obsidian-rumdl
• Installed using BRAT: https://github.com/TfTHacker/obsidian42-brat

When I do changes in a note where CTRL+S triggers rumdl format/fix, and rumdl does changes, this highlighter stops highlighting code.

To Reproduce

1. Install this plugin and rumdl.
2. Enable format on save with the rumdl plugin.
3. Create a note with a code block, and add two-three consecutive lines somewhere outside the code block.
4. Save file CTRL+S, which triggers rumdl, which will remove consecutive blank lines.
5. See Shiki highligter stopped highlighting code.

Expected behavior

Highlighting of code should not stop.

Additional context
Add any other context about the problem here.

No source file or test is named. First reproduce the issue with Obsidian, obsidian-shiki-plugin v0.7.7, and rumdl format-on-save, then inspect the plugin's highlighting update path around an externally modified note. Done means code highlighting remains active after CTRL+S causes rumdl to remove consecutive blank lines.
