AdGuard VPN extension causes blocking of some cross-origin requests

It looks like AdGuard VPN extension causes blocking of some cross-origin requests (for example, requests for some audio tracks on vk.com, where VPN is disabled). No other add-ons, and this problem does not occur when AdGuard VPN extension is disabled.

Steps to reproduce:
Open a new Chrome or Firefox profile, install AdGuard VPN extension, register a free account.
For VPN country, choose Luxembourg, Netherlands, Poland or Turkey; disable VPN for vk.com.
Try to play these tracks (under “Все аудиозаписи”): https://vk.com/audio?q=%D0%B0

Extension version: 1.3.42
Browsers: Chrome, Firefox 108.0.2
Platform: Windows 10, different computers
