AGTree does not accept `$` character in a modifier that aceepts

[piquark6046]

AGTree does not accept $ character in a modifier that aceepts $ character in filter spec.

For example, I can see the bug with the following filter:

||example.com^$removeparam=id$
||example.com^$removeparam=/^id\$$/

This is an interesting issue, it happens because the $$ sequence takes precedence over network rules, as it is a cosmetic separator
