5. Let src be R.[[OriginalSource]].
6. Let flags be R.[[OriginalFlags]].
7. Return EscapeRegExpPattern(src, flags).
21.2.3.2.4 Runtime Semantics: EscapeRegExpPattern
[...] The code points / or any LineTerminator occurring in the pattern
shall be escaped in S as necessary to ensure that the String value
formed by concatenating the Strings "/", S, "/", and F can be parsed
(in an appropriate lexical context) as a RegularExpressionLiteral that
behaves identically to the constructed regular expression.
