Steps to reproduce

1.  Create a rich text field component
2.  Click on Link to Internal Page or Link to DAM document
3. Close without selecting anything
4. Check that the rich text has 0.2 opacity
   

Expected results

0.2 opacity attribute is removed from the editor

Actual results

The opacity attribute is only removed when a page or a DAM document is selected

Workaround

N/A

Development notes

When a page or DAM document is selected, there is a call to:

function setReadOnly(editor, isReadOnly) {
    if (isReadOnly) {
        editor.element.setStyle('opacity', '0.2');
    } else {
        editor.element.removeStyle('opacity');
    }
}

And this is done through:

 editor.on(EVENT_SEND_MAGNOLIA_LINK, function(e) {
     deselectedCommand();
     setReadOnly(editor, false);
[...]

The problem is that hen you click on the X icon (close dialog) or at "Cancel" button, the editor.on(EVENT_CANCEL_LINK, function(e) is not being called so the opacity can't be fixed.
