Description
In the case of a state hierarchy like parent -> child -> [grandchild1, grandchild2] if you call $state.go('.grandchild2') in the child controller and you navigate directly to parent.child the ui-sref-active for the grandchild is NOT activated. If, however, you call $state.go('.child.grandchild2') in the parent controller and you navigate directly to parent the ui-sref-active for the grandchild IS activated.
This issue is not present in v0.3.1.
In the plunker you can test the different flows by commenting/uncommenting the go calls in the controllers and clicking on the appropriate links. I also included a commented out script reference in index.html to v0.3.1 so you can see that it used to work.
One thing I found is that if you wrap the $state.go call in the child controller with a timeout it works as expected.
