When using the link attributes → module in combination with Extlink, Extlink is overriding the title which is entered by the user.
1. Install Extlink and
https://www.drupal.org/project/link_attributes →
2. Configure a Link field and choose the widget "Link (with attributes)"
3. Create content with the link field, add a custom link title
4. See the link title is replaced with "(opens in a new window)"
I think the title "(opens in a new window)" is not required on the link. The extlink icon itself already has a title.
Other idea: Check if the link already has a title text and don't override it in this case.
