Automatic update from web-platform-tests Fix ReadableStream.from ignores a null @@asyncIterator The proposal uses TC39 [GetIterator][] and [GetMethod][] within it. GetMethod treats null as undefined. So if `@@asyncIterator` is null it should be ignored and fallback to `@@iterator`. This change breaks Deno v1.43.5 and Node v20.13.1. However, Firefox 126.0 are implemented correctly.

Streams Tests
The work on the streams tests is closely tracked by the specification authors, who maintain a reference implementation intended to match the spec line-by-line while passing all of these tests. See the whatwg/streams repository for details. Some tests may be in that repository while the spec sections they test are still undergoing heavy churn.
