Using `fluid.rootResolveSingle` as a subcomponent does not result in a single instance of the grade.

Description

I have put an example up on CodePen, which is:

fluid.defaults("examples.rootComponent1", { gradeNames: ["fluid.modelComponent", "fluid.resolveRootSingle"], singleRootType: "examples.rootComponent1", model: { value: "root component defaults" } }); fluid.defaults("examples.rootHolder", { gradeNames: ["fluid.modelComponent"], components: { rootComponent: { type: "examples.rootComponent1" } }, model: { value: "{rootComponent}.model.value" } }); var that1 = examples.rootHolder(); console.log("Component model value before change: " + that1.model.value); that1.applier.change("value", "change applied by first parent"); console.log("Root model value following relayable change: " + that1.model.value); var that2 = examples.rootHolder(); console.log("Root model value of first component following creation of second parent: " + that1.model.value); console.log("Root model value of second component following creation of second parent: " + that2.model.value); that2.applier.change("value", "change applied by first parent"); console.log("Root model value of first component following change by second component: " + that1.model.value); console.log("Root model value of second component following change by second component: " + that2.model.value); that1.rootComponent.applier.change("value", "change applied from root subcomponent"); console.log("Root model value of first component following change by root component: " + that1.model.value); console.log("Root model value of second component following change by root component: " + that2.model.value); that1.destroy(); that2.destroy();

This outputs:

"Root model value of second component following creation of second parent: root component defaults" "Root model value of first component following change by second component: change applied by first parent" "Root model value of second component following change by second component: change applied by first parent" "Root model value of first component following change by root component: change applied from root subcomponent" "Root model value of second component following change by root component: change applied by first parent"

From these examples it seems like each subcomponent that uses `fluid.resolveRootSingle` becomes in essence like an ordinary `fluid.modelComponent`. The second one instantiated does not replace the first, and each only relays to and from its parent in its own component tree.

As we've discussed in the chats, I want to have a `fluid.resolveRootSingle` grade as a subcomponent to ensure that the first component that needs the grade causes it to come into existence.
