Scripts can't be unblocked with custom filters

[wooque]

Description

I want to block scripts in general and only allow certain scripts to be run. For test I blocked scripts on https://boards.4channel.org/g/catalog, and added exceptions in custom filters

@@||s.4cdn.org/js/*$script
@@||boards.4channel.org^$inline-script

but that didn't work.

Steps to Reproduce

1. Block scripts on https://boards.4channel.org/g/catalog
2. Add custom filters

@@||s.4cdn.org/js/*$script
@@||boards.4channel.org^$inline-script

Actual result:

Scripts are still blocked

Expected result:

Scripts are unblocked

@wooque this is by design, we don't want users who enable script blocking to be affected by exceptions written specifically for selective adblock filtering (which can be shipped by upstream filter list authors).

The good news though, is that we recently landed selective script blocking exceptions through the shields panel in Nightly - see brave/brave-core#17221 for details.
