The way the faking works is that the site catches your click event and redirects you to somewhere else. Therefore, the only fix is to prevent such redirects. Preventing JS redirects would break many things. AJAX form submission with a redirect at the end, for example, is very common.
Preventing them in onclick handlers of a[href] elements would break fewer, but then you have the issue of correlating the redirect with the click. If you simply ban window.href= in the handler, sites could simply use setTimeout or set a flag and have a repeating background task trigger the redirect when the flag is set. Alternatively, you could do something like prevent all redirects X seconds after a link is clicked. Unfortunately, that would only discourage sites that are trying to be fast (like Google). Scam sites are usually slow and bloated anyways.
The trick works by cancelling the link click event and redirecting somewhere else in JS. The only way to prevent that would be to not allow any redirects in JS, including buttons.
What use cases would it break? Why do you need a fake URL to show up when the link is hovered?
