Suboptimal treeshaking on pure function calls

[intrnl]

It doesn't seem like esbuild is removing these pure function calls

import { html, clone, first_child, append, define } from "@intrnl/velvet/internal";
let template0 = /*#__PURE__*/ html("<div>hello</div>");

function setup($$root, $$host) {
	let fragment0 = /*#__PURE__*/ clone(template0);

        // these are deliberately commented out, though they are relevant
	// let child0 = /*#__PURE__*/ first_child(fragment0);
	// let child1 = /*#__PURE__*/ first_child(child0);
	// append($$root, fragment0);
}

export default define("x-app", setup, {}, []);

Does it matter if the REPL has said import externalized?
