Clicking on a mailto link brings up an xdg-open dialog every time. Even though there’s a check box to allow the site to xdg-open the mailto link it prompts every time. IOW the toggle is not respected or saved. Additionally, I don’t think having to allow each and every site that might have a mailto link that I want to use is the right way to do this. There should be a setting to allow all sites permission to use mailto links.
