Many DNS requests in short time cause problem with internet connection

[AdamWr]

Steps to reproduce

1. Enable DNS Protection in AdGuard for Windows app
2. Run this program - https://www.grc.com/dns/benchmark.htm

After a while there is a problem with internet connection and opening any website causes that DNS_PROBE_FINISHED_NO_INTERNET error is displayed.

I have to disable AdGuard protection to fix this problem.

If I'm not wrong, it's not a new issue and the same problem occurs with previous version of AdGuard for Windows app.

AdGuard for Windows version 7.9 nightly 4 (build 3793, CL 1.9.5)
