Both Safari and IE take at most the first three octal digits, so they would
interpret it as [\0 1 1]. Only Mozilla would act as this test expects. Should we
match Safari (or the majority) here?

I don't really have an opinion.  We could also follow the spec.

   ExpectParse("[\\118]", "[\t 8]");
   ExpectParse("[\\111]", "[I]");
   ExpectParse("[\\1111]", "[I 1]");
