Plugin to send early beacons Non-SPA: Send when config is loaded (onconfig event) if:
- after DOMContentLoaded
- before onload
- not in prerender
- autorun is true
- not a reload or back/forward navigation
If we were in prerender, send when visible (prerender_to_visible event) if config was received and the conditions above are met. If onconfig fired before DOMContentLoaded, try again when DOMContentLoaded fires.
SPA: Send when the count of resources we're waiting for drops to 0 for the first time + SPA_EARLY_TIMEOUT (controlled by AutoXHR plugin) and if:
- not in prerender
- not a reload or back/forward navigation Current limitations:
- Does not check if before DOMContentLoaded.
- Does not retry sending at prerender_to_visible event.
