Issue with group backreference by name

RegExr recognize naming of capturing group, however at the same time when i try to refer to named group with '\k<groupName>' it counts '\k' as escaped character. image

Both PCRE2 and javascript do not support \k

It's unclear to me why this was closed – javascript does support \k:

But this tool still does not recognize \k as anything other than an escaped k:

It does appear that \k support has been added in the intervening years. Opening this back up. Given that we have support for it in PCRE, this should be an easy addition.
