As one user in the WordPress support forums for Site Kit kindly pointed out there is a dead link at present (within the PageSpeed Insights Widget) - with Site Kit using the related PSI/Lighthouse API. I was able to replicate this performing a Lighthouse audit within Chrome (on a WordPress site)

The link at present is: https://developers.google.com/web/updates/2017/04/devtools-release-notes#coverage
The link should possibly be changed to: https://developer.chrome.com/docs/devtools/coverage/

Provide the steps to reproduce

1. Run LH on a WordPress site using Chrome Dev tools
2. If Unused CSS is listed as an opportunity click on the "Code Coverage" link

What is the current behavior?

The Code Coverage link points to a dead link

What is the expected behavior?

The link should point to an appropriate link
