Hi Yikai,
Thanks you for reporting this bug. I was able to confirm it, and trying a few
similar such buffers can also say this only appears to affect `markdown-mode'.
I’ve prepared a patch that serves as a catch-all for this type of issue, but I’m
not sure if this is the best approach. If other people could chime in that would
be great :)
All the best,
Timothy
