- Create a local page we will access via an about: URL - In that page, demonstrate how to do some stuff, then fire a custom event indicating its stuff is done _and_ return complex data in that event. console.log() didn't seem to be visible in the HiddenWindow, so I also piped out debug strings for development purposes, so they can be console.logged in the Service, where we can see them. - Instead of listening for DOMContentLoaded/pageshow, instead listen for the new CustomEvent. - In UserCharacteristicsPageService, receive the data from the page and populate the appropriate Glean metrics - Refactor the calling of nsUserCharacteristics::PopulateData() and SubmitPing(). Now we call PopulateDataAndEventuallySubmit() which will eventually call SubmitPing after our promise is resolved. - To make it a little cleaner (so ContentPageStuff() isn't calling SubmitPing()) we return the promise out of ContentPageStuff() that PopulateDataAndEventuallySubmit() will await and then call SubmitPing() when that promise resolves Differential Revision: https://phabricator.services.mozilla.com/D203055
