I have been using the kitchen sink example and have a basic set-up with a master-detail view. This works fine: https://codepen.io/pconkie/pen/rNLjQaa. It uses a standard link to load the master page and the breakpoint is observed.
var mainView = app.views.create(".view-main"); mainView.router.navigate("/projects/");
the page works, but is no longer split master / details on screens wider than the breakpoint.
Why is this?
