/**
* 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
