- Tests that lookahead and lookbehind are not extended to QuantifiableAssertion, as in https://github.com/tc39/ecma262/pull/1102 - Additional tests verifying some more combinations of cases for QuantifiableAssertion being invalid in Unicode mode. Based on the tests in https://chromium-review.googlesource.com/c/v8/v8/+/926102 These tests pass on V8 (if the throw for early errors is removed to work around a V8 issue where RegExps don't have early errors).
