Linkit not working with CkEditor I have installed the Linkit module to a test site.

I have created a profile, set Matchers and created attributes. I have gone into the CKEditor configuration and chosen my Linkit profile, added the Linkit button, saved the configuration and then liberally cleared the cache on my test site (Vagrant running a lamp stack and Drupal 8.)

When I attempt to use the Linkit feature on either a new piece of content, or an existing one, the dialog box appears with all the desired options, however, other than the standard CKEditor link behaviour none of the other attributes work. I cannot set the title, I cannot set the target attribute.

No errors are appearing in the log and I can find no similar problems on line. 

Can anyone suggest a reason this is occurring?
If the filter not Full HTML, you will need to edit the filter format and enter the attributes on the anchor tag in the settings. If not, they will be stripped out (for security reasons).
