Error detection using markup on browser extension

I have observed this behavior in the Chrome/Firefox extensions when using markup text:

  • [[errors here are ignord]]
  • [errors here are ignord](http://ignorederrorsexample.com)
  • [errors here are NOT ignord]

imatge

It doesn’t make sense for me. What is the purpose?

A more useful approach would be:

  • [[errors here are NOT ignord]]
  • [[errors here are ignord|errors here are NOT ignord]] (for Wikipedia markup)
  • [errors here are NOT ignord](http://ignorederrorsexample.com)
  • [error here are NOT ignord]

What do you think?

I think it is a bug. I will have a look soon.
