Created attachment 8673141 [details] [diff] [review] explicit-homepanel-loadurl v0.1 We have been using the Session telemetry to figure out the LOAD_URL/LIST_ITEM source panel. This should work fine, but I am a little worried that my post-processing scripts could be getting confused by the fact that we can display Home Panels on top of Home Panels, creating a nesting of panel sessions. I mean, it's OK to open about:home (which creates a Session) and then tap the URL bar (which opens a different Home Panel and creates a different Session). By tagging the Telemetry with an Extra, we can be more accurate.
