🐛 Fix error when get-parent-with-data encounters non-Element nodes

The get-parent-with-data function traverses the DOM using parentElement
to find an ancestor with a specific data-* attribute. When the current
node is a non-Element DOM node (e.g. Document node reached from event
handlers on window), accessing .-dataset returns undefined, causing
obj/in? to throw "right-hand side of 'in' should be an object".

This adds a nodeType check to skip non-Element nodes during traversal
and continue up the parent chain.
