[ckeditor] Linking to email doesn't add the "mailto" code

I'm having the same issue. When manually entering an email address (not matching an existing one) the link becomes:

<a href="myemail@address.com">Link text</a>

Confirming that a `E-mail`-matcher enabled profile does not prepend a `mailto:`.

For this to work, you have to enable the E-mail matcher, and also actually use it (click on the autocomplete suggestion).

The other behavior is not Linkit, its is Drupal Link plugin that is bundled with core. Unfortunately there is nothing I can do about it.

Please feel free to open and move this issue to that project.
