Bug Summary

PWAs report incorrect URLs to extensions. In this example, Bitwarden is showing me GitHub logins on Feishin, even though it's supposed to be showing my Navidrome login and does so when Feishin is not open as a PWA

Reproduction Steps

1. Open a website as a PWA
2. Try to use an extension that uses related API calls (not an extension dev)

Expected Behavior

Same behavior as when site is not open as a PWA

Actual Behavior

See Bug Summary

Screenshots

Browser Version

11.18.1 (64-bit)

Operating System

Arch Linux (Tested on NixOS Unstable as well)

Additional Context

I am aware that PWAs are still experimental and I am not expecting this issue to be resolved quickly. Just reporting it because I have not found it among reported issues and it does degrade my experience of using this otherwise wonderful browser.
