2 years ago Gecko has something like this, but instead of passing in source text you pass in a function. Maybe we could have an API like
test_driver.execute_script(callable, {args: []})e.g.
test_driver.execute_script(async (elem_id) => {
await new Promise(resolve => setTimeout(resolve, 0));
return document.getElementById(elem_id).innerHTML
}, {args: ["test"]})If the function returns a promise, we always await the promise, if it returns a value we always just return the value.
On the backend, we'd toString() the function and json-encode the args and do something like
webdriver.execute_async_script(f"""
let callback = arguments[arguments.length - 1];
let result = ({function_string}).apply(null, {json.loads(args_array)});
Promise.resolve(result).then(callback);
""")

This provides a direct way to execute script in another browsing context.
