Describe the bug

Lighthouse shows the error "Browser errors were logged to the console".

The description of the error is "Access to XMLHttpRequest at 'https://clientapi.passle.it/CookieControlPlugin/CookieControl' from origin 'https://environment.johnbosley.dev' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."

The resource at https://clientapi.passle.it/CookieControlPlugin/CookieControl has the header Access-Control-Allow-Origin: *, and the console error reported is not logged when visiting the URL https://environment.johnbosley.dev in the browser.

This issue doesn't occur when testing using the devtools, but it does occur when using web.dev.

To Reproduce

Steps to reproduce the behavior:

1. Run web.dev on https://environment.johnbosley.dev/ and view the report.

Expected behavior

The best practices section shouldn't show any errors.

I think this might be a PSI issue. Moving over to the LH repo as they also manage PSI.
