Description
### Prerequisites
- [x] I am running the latest version
- [x] I checked the documentation and found no answer
- [x] I checked to make sure that this issue has not already been filed
### Issue Details
- **AdGuard version:**
- Adguard Pro/Adguard 4.0.1
- **Device model and storage size:**
- iPhone 8 Plus
- **Operating system and version:**
- iOS 13.5.1
### Actual Behavior
When I checked the access log, I found that the AAAA query types were double-checked if there was a CNAME record in the response, while with query type A it was completely unavailable.
So is the application trying to solve 2 times in AAAA records?
For responses with CNAME records, type A will not resolve further, while AAAA types will continue to resolve but are blocked. I see this may not be blocked because in the previous query response there were CNAME and IP records, the application continued to resolve CNAME but was blocked?
