Description
Hey @Belco90
I just upgraded to the new version that fixed #367, and I am reporting that it indeed reported new cases...but not all of them!
For example these cases aren't reported still: https://github.com/firefox-devtools/profiler/blob/1c5dfed055f864413b3a62e43ca2d27b074d6108/src/test/components/CallNodeContextMenu.test.js#L107-L112
I'm pretty sure this is because of the spread operator. And indeed I reproduced by slightly adjusting one of the smaller testcases:
import * as React from 'react';
import { render } from 'firefox-profiler/test/fixtures/testing-library';
function setup() {
const result = render(<div />);
return { ...result };
}
it('detected', async () => {
const { getByText } = await setup();
expect(getByText('foo')).toBeInTheDocument(); // detected
});
it('undetected', () => {
const { getByText } = setup();
expect(getByText('foo')).toBeInTheDocument(); // undetected
});
Hope this helps :-)

Research direction
Start by reproducing the rule against the cases in src/test/components/CallNodeContextMenu.test.js, lines 107-112, and the reduced setup example using the spread operator. Trace how setup's returned properties are resolved, then verify that both getByText cases are reported while preserving the existing detected case.
