How to avoid URLs with "unsafe" prefix

[arvid-r]

Hi!
We generate links to build artifacts in our build steps, but also custom links that open a certain local application, much like a link that opens Spotify or Zoom etc. However, AngularJS (I believe) adds a prefix, so the link is rendered useless and comes out something like this: unsafe:myapp://buildserver.com/thebuild/description.json rather than just myapp://buildserver.com/thebuild/description.json
Can this be avoided somehow? Or do I need to fork Buildbot and hack around in the frontend code to get around this?
