When trying to format this markdown document, VS Code fails with the error message:
Command 'Format Document' resulted in an error (Overlapping ranges are not allowed!)

With a clean install of VS Code and only yzhang.markdown-all-in-one installed, invoking "Format Document" on this markdown document should result in the above error.
Command 'Format Document' resulted in an error (Overlapping ranges are not allowed!)

Thanks for the feedback.
The reason is you have two identical tables.
It should be fixed in the dev build.
Be careful. There is a serious bug.
Resolved.
Awesome, thanks @yzhang-gh!
