Spread operator not supported in function call

The following code fails to be transformed:

async function foo() {
  bar(...await x);
}

See this babel repl.

Exception occurs at the assertion here:

regenerator/packages/regenerator-transform/src/emit.js

Lines 903 to 910 in a755f3f

	Ep.explodeExpression = function(path, ignoreResult) {
	const t = util.getTypes();
	let expr = path.node;
	if (expr) {
	t.assertExpression(expr);
	} else {
	return expr;
	}

Expected type "Expression" with option {}, but instead got "SpreadElement"
