Description

When loading a Gitea instance after the service worker got installed, xhr requests are not shown in the dashboard.

A specific URL where the issue occurs

https://gitea.com/golang/go

Steps to Reproduce

1. Load page once
2. Reload with F5
3. open dashboard and there are no xhr requests for secure.gravatar.com

Ruleset

Supporting evidence

If you block XHR for secure.gravatar.com and reload the page with F5 you are missing avatars (see below) but the dashboard does not report that despite it being logged (seen in the logger screenshot above).

Also the following gets logged and you have no idea why and think your CSP is broken for 3 hours.

Your environment

• uMatrix version: 1.4.0
• Browser Name and version: Chrome 80.0.3987.149
• Operating System and version: Windows 10 Pro 1909 18363.752

Tabless requests will never appear in the popup UI panel of uMatrix/uBO.

Tabless requests will never appear in the popup UI panel of uMatrix/uBO.

Why will they not appear? In this scenario the service worker will only work when it intercepts a request from the current tab and to hide that makes no sense. They are logged and could be shown in the dashboard belonging to the current tab.
