I am writing to follow up on this open bug report as it continues to significantly impact our company’s work. Specifically, one of our customers relies on the document.referrer value to be set when navigating to subpages. However, when requests go through our service worker, this property is always empty, causing issues on our customer’s website.

We would greatly appreciate any assistance in resolving this issue as soon as possible.
