HTMLCollection.forEach is not a function

[bradfrosty]

Product: axe-core

Expectation: Element.children does not use forEach directly

Actual: Element.children is relying on incorrect polyfill (fixed in core-js here)

Offending code is here

Motivation: This will eventually be broken when core-js is upgraded for axe-core via Babel

axe-core version: 4.3.3
axe-webdriver, extension or other integration version: n/a

Browser and Assistive Technology versions

For Tooling issues:
- Node version: 16
- Platform: Mac

Additional info

There are a few other references to children.forEach from the internal VirtualNode class. These treat children as actual arrays, and not the "array-like" HTMLCollection.

VirtualNode is not a Node, it has a proper array for children as can be seen in the constructor
