.filter(filterNode) passes (element, index, array) to filterNode, but filterNode expects only (node: Node). Wrapping with an arrow function ensures only the element is passed, preventing unexpected behavior when the Array.prototype.filter callback arguments are misinterpreted. Fixes testing-library#1360

Fixes #1360
When printing filtered DOM nodes, Array.prototype.filter passes three arguments (element, index, array) to the callback, but filterNode expects only (node: Node). While this works in JS due to ignored extra arguments, wrapping with an explicit arrow function
.filter(node => filterNode(node))ensures only the element is passed, matching the type signature.
