[Bug]: expect().toEqual does not compare unique node properties

[mozesstumpf]

Version

29.5.0

Steps to reproduce

it("tests the node's properties", () => {
	const text1 = document.createTextNode("text");
	text1.customProperty = "customProperty";

	const text2 = document.createTextNode("text");

	expect(text1).toEqual(text2); // Passed
});

Expected behavior

Test should fail since the text1 has a custom property.

Actual behavior

The expect().toEqual method can't detect the custom properties on the Node, same goes for the toStrictEqual.

Additional context
