Upgrade to RRWeb 2

[benjackwhite]

Is your feature request related to a problem?

RRWeb 2 is still in alpha but for many customers it appears that it would already provide an improved experience thanks to the number of bugfixes and improvements only found in that version

Describe the solution you'd like

If we implement PostHog/posthog-js#523 then we can create multiple exported bundles of the rrweb recorder, and allow the frontend to load the appropriate recorder, depending on some config (probably client side for now).

We could simplify the logic in posthog as we would simply be copying the dist from posthog-js.

Describe alternatives you've considered

Additional context

Related issues that are blocked due to rrweb version:

• Console logs can cause infinite loop when logging objects with a Proxy posthog-js#517
• The currently used rrweb version causes custom tag HTML elements' innerHTML to be attached to shadow-roots posthog-js#514
• PostHog session recording only captures first section on the page of about 8 sections revealed on scrolled. #12690
• Screen recording does not work with shadow DOM #13255
• Recordings don't render a scroll that doesn't happen on the body. #10021

Thank you for your feature request – we love each and every one!

Remaining tasks

• Setup posthog.com page detailing Recorder V2, how to opt in and what to expect @benjackwhite
• Turn on Recorder V2 for new projects @benjackwhite
• Email campaign for existing Recording users on V1
• Rollout by "force" for all customers with clear indication of how they can rollback if they encounter issues
