Status: RESOLVED WONTFIX

(Remote Protocol :: CDP, defect, P3)

Description

[Maja Frydrychowicz :impossibus (was :maja_zf) (needinfo me)]

We don't emit any events in this case.

Maja, your example above doesn't show any lifecycle event, but just page load events. Maybe you used the wrong term in the bug summary?

Comment 2

[Maja Frydrychowicz :impossibus (was :maja_zf) (needinfo me)]

Yeah, I mean the general term "page life cycle" (for load, DOMContentloaded) rather than the CDP-specific Page.lifecycleEvent

Maybe wrapping the request into a new http channel might give us some events? There is code in devtools we could have a look at:

We are not going to implement support for this for our CDP implementation.
