Cannot transpile yield/await spread for Firefox 47 #12690
Description
Bug Report
Current behavior
import Component from '@glimmer/component';
import intersection from 'lodash/intersection';
export default class FooComponent extends Component {
async foo() {
intersection(...(await Promise.all([])));
}
}Expected behavior
Code to be transpiled correctly.
Currently Babel blows up with:
Expected type "Expression" with option undefined, but instead got "SpreadElement".
Using firefox 35 for targets works. As does firefox 53 and above.
