Description Mattias Buelens 2022-01-13 13:46:18 PST 
Previously, calling ReadableStreamDefaultReader.releaseLock() or ReadableStreamBYOBReader.releaseLock() while there are pending read() requests would throw a TypeError.
The specification has been changed to allow this case, and to reject such pending read() requests instead.

Standard change: https://github.com/whatwg/streams/pull/1168
Tests: https://github.com/web-platform-tests/wpt/pull/32072
Comment 1 Mattias Buelens 2022-01-13 13:46:57 PST 
We just merged this change into the spec, but we accidentally forgot that this also affects default readers. Since default readers are already implemented in multiple engines, our process mandates that we should have first asked whether WebKit is interested in this spec change. Our apologies.

If you have any objections, please let us know in https://github.com/whatwg/streams/pull/1168
