Here we remove the callback from the emit preferring to make it async instead.
This work precipitated by the deprecation of callbacks when we emit from plugins.

Method evaluates the calculation called for by its markup during the emit. This evaluation expects a callback itself. This is where display update happens such that computations show in the freshly emitted display. We wrap this logic with
new Promise(...)replacing the sole reference to the removed emit parameter with theresolveoffered by the promise.
