Cannot access the clipboard for the crypto address check (wayland)

Noticed after the ESR 128 rebase, and not reproducible in 13.5. Not sure what changed in mozilla-central to cause this.

Steps to reproduce:

1. Visit http.badssl.com.
2. Open the page console and add document.body.append("3aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");.
3. Try to copy the appended text.

In the page console I get:

Uncaught (in promise) DOMException: Clipboard read operation is not allowed.

And the expected crypto warning does not pop up.

I think the CryptoSafetyChild no longer has permission to read the clipboard content.
