--- Comment #3 from Lauro Moura <lmoura at igalia.com> ---
After the last round of stream commits, pipe-to.html keeps failing with this diff (from a Catalina build):

-FAIL Piping to a writable stream that does not consume the writes fast enough exerts backpressure on the source |this| is not a Promise
+FAIL Piping to a writable stream that does not consume the writes fast enough exerts backpressure on the source assert_equals: at t = 0 ms, ws should be writable expected (string) "writable" but got (undefined) undefined

The test still expects WritableStream to have the 'state' attribute, but it is some detail from the reference implementation, not part of the public WritableStraem API, right?

Btw, testing with both GTK and WPE removing the state check fails at 225ms with:

-FAIL Piping to a writable stream that does not consume the writes fast enough exerts backpressure on the source |this| is not a Promise
+FAIL Piping to a writable stream that does not consume the writes fast enough exerts backpressure on the source assert_array_equals: at t = 225 ms, the two enqueued chunks in rs did not cause backpressure property 1, expected 1 but got 0
