// In this test we are introducing two widgets. The only difference between them
// is that the first one is using `connectRoot` with the `aTranslate` argument set to `true`,
// and the other one to `false`.
//
// In this test, we will inject both of them into the DOM for parsing.
// For a test that verifies the behavior when they're injected lazily, see
// `test_connectRoot_webcomponent_lazy.html` test.
//
// Since both widgets get injected into DOM during parsing, we expect both of them
// to get translated before `document.l10n.ready` is resolved.
