- * When a `nonce` is present on an element, browsers such as Chrome and Firefox strip it out of the
- * actual HTML attributes for security reasons *when the element is added to the document*. Thus,
- * given two equivalent elements that have nonces, `Element,isEqualNode()` will return false if one
- * of those elements gets added to the document. Although the `element.nonce` property will be the
- * same for both elements, the one that was added to the document will return an empty string for
- * its nonce HTML attribute value.
- *
- * This custom `isEqualNode()` function therefore removes the nonce value from the `newTag` before
- * comparing it to `oldTag`, restoring it afterwards.
- *
- * For more information, see:
- * https://bugs.chromium.org/p/chromium/issues/detail?id=1211471#c12
