Params not passing from react context

[chargrove]

I'm migrating an AngularJS application and replacing pieces with React components. These components have UISref links within the application and include parameters. The values of these parameters never seems to feed through to the deeper context though.

I've created a simpler test case of the issue:
https://stackblitz.com/edit/ui-router-react-hybrid-objparam

The routes at the top all set two params and they seem to work, but this is from an AngularJS context. If you choose one of the react states and then click one of the links further down the page, the parameters there never feed through and only null shows up.
