Similar to the fuzzer bug found in https://bugs.webkit.org/show_bug.cgi?id=223498 - "[YARR] Interpreter incorrectly matches non-BMP characters with multiple .", there is a similar issue when the dotAll flag (s) is used. String.fromCodePoint(0x10000).match(/../u) should not match but does in the Yarr Interpreter.
