Civicrm Removing AngularJS url
I don't think that is possible, but not for the reason you think. The problem is not whether or not the link gets rendered correctly, the problem is that AngularJS expects to launch a single-page-app, not load an html snippet into a tab. If you need to link to an angular page, you will need to do so as an actual link, and it will have to take the user away from the contact summary page and over to the angular page.
