What issue do you have?

Markdown syntax cannot be rendered correctly when text contains colon, whether it is a full-width or half-width colon.
Only when a space is added at the end of the syntax can the text be rendered correctly.
Is there a problem with this? Thank you!

It's not just the rendered text, the editor shows it incorrectly as well. "No space" has the entire line bold rather than just the enclosed text. I turned off all the markdown options (math, linkify etc.) and it makes no difference

And it's not just the colon. Any non-alphanumeric character does the same thing.
