1. Add to user rules:

@@||example.org^$generichide
||example.org^$document

2. Go to - http://example.org/

Webpage is blocked due to ||example.org^$document. This would be consistent with the CoreLibs app and MV3 extension (available in v5.2)

Actual Behavior

$document blocking rule is not applied, because an exception rule is applied since it has higher priority:
