Yes, wasm is a pretty fresh compilation target; I'll take a look at that problem in the near future.

Fixed in 2.0 (branch
rewrite, ships with 2.0.0-dev.1). The browser transport was rewritten onpackage:webanddart:js_interop, and messages are received under dart2wasm: the full browser suite, including end-to-end tests against a real server (text, binary, JSON, large and fragmented messages), runs in Chrome under both dart2js and dart2wasm on every CI run (web_server_test.dart, web_transport_test.dart).
