The WPT test "ReadableStream teeing: erroring a teed stream should properly handle canceled branches" was improved in https://github.com/web-platform-tests/wpt/pull/28153. The test now checks that the cancel promises of the two branches are rejected with the correct reason. This updated test fails in Safari, see: https://wpt.fyi/results/streams/readable-streams/tee.any.html?diff&filter=ADC&run_id=5700976721788928&run_id=5767793259577344 Chrome, Edge and Firefox still pass the updated test.
