Allow listening to suggestion being selected

This change seems to have caused some very specific regression within the ckeditor linkit widget.
When a link to a specific item was made, and you try to add that same link again; it will not be selected.

Steps to reproduce:

1. Create a node to link to, title example: "My page"
2. Create a link to "My page" in any ckeditor widget; via the linkit autocomplete selection, it will automatically be replaced to /node/1.
3. Enter "My page" again in the autocomplete widget. After selection, it will not be replaced to /node/1. The autocomplete search query will stay in the link field. Any other autocomplete result will work just fine, however.

When using linkit 6.1.2, this works as expected.
When using 6.1.2 + this patched diff (or 6.1.3), I'm seeing the above described behavior.

Okay, thanks for reporting this! I've created a new issue to track the resolution: 🐛 [Regression] Previously selected link cannot be selected again after #3422951 Active
