Issue Details

Steps to reproduce:

1. Enable AdGuard DNS only without Safari protection
2. Go to https://www.facebook.com/BFMTV/?_rdr
3. Click on any link to this media's website (looks like: https://l.bfmtv.com/...)
4. You will see "Content blocker preventing page from loading".
5. Go to allowlist and type: l.bfmtv.com domain
6. Repeat steps 2 and 3
7. You will see "Safari can't open the page because the address is invalid".

(if I change the DNS server to AdGuard Personal DNS - everything seems fine, in Desktop AdGuard allowlist works as expected)

Expected Behavior

The allow list should unblock l.bfmtv.com and redirect to bfmtv.com.

Actual Behavior

Safari can't open the page because the address is invalid
