While similar changes in the past have not resulted in user-visible changes (since implementations must already ignore resolving already-resolved promises), this particular case *does* lead to a behavior change (which is covered by new WPT tests). See https://github.com/whatwg/streams/pull/1118 for the specification change and https://github.com/web-platform-tests/wpt/pull/28266 for the new tests. 1747670 1 webkit-bug-importer 2021-04-06 15:22:13 -0700 <rdar://problem/76286913> 1914289 2 youennf 2022-11-23 02:50:06 -0800 Added test is passing, implementation works as expected.
