setTimeout is always unfortunate: it places a lower bound on the time required
for the test to complete. Please use setTimeout 0 or redesign the test to not
require it: e.g., call addEventListener() inside an install event handler.

Done.

+console.log('Here is in the first execution.');

I think you could simplify the test by removing these console.logs.

Done.
