Support recording content from cross-origin iframes

[TheChoconut]

Any chance of supporting the recordCrossOriginIframes feature from rrweb?

Currently trying to use the Session Replay feature to record events on the site and a widget rendered inside an iframe.
It seems that it is currently not possible to pass this option to the recorder. This makes it impossible to record events in cross-origin iframes and iframe content is not rendered in the replay player.

It would be great if it was possible to merge recordings from iframe and host page into one session.

Don't recall why this was left out. @billyvg you know?

We can add in the options and have it default to off.

But was there a security concern or some other reason we kept it out or it was just to trim down the initial options?

Hello everyone! Any solution to it?

Don't think we prioritized this one tbqh. cc @jas-kas
If there's no security concern, we can expose the options as @billyvg suggested.
