Observed directly from this connection's TLS ClientHello. Nothing here comes from JavaScript.
This client may not implement or enable the Trust Anchor IDs extension.
The current ClientHello did not contain experimental extension 0xca34. This does not prove the client has no trust anchors; it only means none were advertised through this mechanism on this connection.
