JS error in J3.6.5 backend

[ste...@gmail.com]

Seems a recent update to IE 11 has caused a JS error to pop up in validate.js.

Forms will not save if the form contains an email address.

Object doesn't support property or method 'toASCII'

t=punycode.toASCII(t)

Works fine in edge, chrome and Firefox, anyone else noticing this?
