Bug 1
Recorder generates error data while recording some websites are integrated with stripe
These websites will usually have an iframe with src "https://js.stripe.com/v3/m-outer-xxx.html"
Reason
The Stripe site has nested iframes and they all have a message proxy to forward messages from child iframe to parent iframe. So cross-origin rrweb messages are also forwarded by this hidden proxy and it makes the recorder generate redundant iframe full snapshots.
Fix
Add an
origin
property to each cross-origin rrweb message for the parent frame to check the integrity of messages.Bug 2
fixes #1077
As Justin's suggestion #1077 (comment), I disabled packing for inter-iframe communication.
