Conflict with Dr.Web Security Space 12.0

[Alex-302]

Steps to reproduce

1. Install Dr.Web Security Space 12.0
2. Add ##body for test element hiding or enable legacy Assistant
3. Open any site.

Expected behavior

Blank page when ##body enabled

Actual behavior

AdGuard injections are not working if Spider Gate in Dr.Web Security Space 12.0 enabled, so element hiding, JS end extensions are not working. Enabling Use redirect mode does not help.
Same issue as #3791
