Failed to render Markdown

Hi Tuan,

Thank you for reporting it.
But I’m afraid that I couldn’t reproduce this problem.
If you found additional information to reproduce it, please let me know.

This happens after I used TOC and latex plugins. It doesn’t happy consistently so even I cannot get what causes this, even something the preview page stops updating even I was editing.
After reloading several times, it will become normal.
