A JavaScript framework for creating ambitious web applications

/**
 * Every renderer that has at least one live root.
 *
 * This covers each application's `renderer:-dom`
 * and every renderer that `renderComponent` created.

 * It lives in its own module so that `@ember/debug`

  Ember Inspector calls this function to capture the current render tree.

  The result has the tree of every renderer with live roots:
  each application, and each `renderComponent` call, whatever its owner.

  In production mode, this requires turning on `ENV._DEBUG_RENDER_TREE`
  before loading Ember.
