Steps to reproduce:

1. Disable all filters
2. Disable all Stealth Mode options, except Hide Referrer from third parties
3. Open https://www.foxnews.com/

Actual behavior

Login button is broken

Various, including generic, $stealth exclusions don't work. Only disabling Hide Referrer from third parties helps.

Expected behavior

Login button is not broken

Not reproduced with AdGuard for Windows.
