Markdown editor: Invalid link silently breaks text

[singharpita]

try to add any link and hit the submit button. but nothing is shown with console error

This is an invalid markdown link. The text is in the brackets and link is in parentheses.

Regardless, this error should be handled better with the markdown rejected in the form rather than submitted to the database.

I only see the error when (http://) is submitted, but there may be other invalid urls.

It might be best to validate the markdown and throw an error that says "Please use valid link(s)".

The validation should match (http://) and any number of spaces between the parentheses and http://
