OS: Windows 10 64-bit
Opera GX Version: LVL2 (core: 73.0.3856.434) I think, not 100% sure how to check

With the "AdBlock warning removal" list selected, the Adblocker overcompensates and ends up removing most of the page itself.

Sorry if this is not enough info, I'm not very tech savvy.

Steps to reproduce:

1. Activate the "AdBlock warning removal" list
2. Go to any webpage with Adblocker enabled
3. Refresh

Poking around the only thing affecting it for me was this list.
