Behavior when pattern is a string describing an invalid pattern (unicode)

[...]
5. Return ? RegExpInitialize(O, P, F).
21.2.3.2.2 Runtime Semantics: RegExpInitialize
6. If F contains "u", let BMP be false; else let BMP be true.
7. If BMP is true, then
a. Parse P using the grammars in 21.2.1 and interpreting each of its
16-bit elements as a Unicode BMP code point. UTF-16 decoding is not
applied to the elements. The goal symbol for the parse is Pattern.
Throw a SyntaxError exception if P did not conform to the grammar, if
any elements of P were not matched by the parse, or if any Early
Error conditions exist.
