What specific section or headline is this issue about?

anchor: #types, heading text: "Types"

What information was incorrect, unhelpful, or incomplete?

The Types section provides a table listing all the different group types, along with their name and a link to details about the type.
The 4th row reads:

(?flags:x), (?:flags-flags:x) | Modifier: Enables or disables the specified flags only to the enclosed pattern. Only the i, m, and s flags can be used in a modifier.

What did you expect to see?

The link to the Modifier leads to:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Regular_expressions/Modifier

on that page the syntax is given as:

(?flags1:pattern)
(?flags1-flags2:pattern)

It seems that the syntax given in the main page:

(?:flags-flags:x)

is wrong - first colon should not be there.

Do you have any supporting links, references, or citations?

Yes, the page that is linked to gives the Modifier syntax:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Regular_expressions/Modifier

which does not match the syntax given in the main page.

Do you have anything more you want to share?
