Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Stencil Version

v4.36.1

Current Behavior

When executing the following code the childNodes property value is an empty Array. The __childNodes property value is a NodeList with a single item. The later is correct, the first not.

let label = document.createElement("ion-label");
label.textContent = "Hello world";
console.log(label.childNodes); // Empty Array
console.log(label.__childNodes); // NodeList with a Text Node

Expected Behavior

The childNodes property value should be the same as the __childNodes result: a NodeList with a single Text Node. The childNodes property value should never be an Array, but always a (live) NodeList for compatibility with the Node interface:
