Bug Report

Bug Description

Injecting any rule, even the ones will not match, would break any websites built with this caseme.io service, including their homepage: https://caseme.io/ (I originally found this bug when visiting another site, https://roitman.io/blog/91.)

There are bunch of errors in console from React:

chunk-WARRYLZU.js:6 Uncaught Error: Minified React error #418; visit https://reactjs.org/docs/error-decoder.html?invariant=418 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

CSS Code

Any rule would break it. E.g.

@-moz-document domain("caseme.io") {
dummy > rule {
    display: none;
}
}

The site explicitly throws on any foreign element added under <html> node. It's the first time I see such a site. As a workaround you can enable Circumvent CSP 'style-­src' via adoptedSty­leSheets in the options.
