Cannot set exemptions to strict blocks

[Alexendoo]

Describe the issue

Setting a filter of example.com$document blocks an entire page, I was trying to unblock a subpage e.g. example.com/page.

both:

example.com$document
@@example.com/page

and

example.com$document
@@example.com/page$document

Resulted in both example.com and example.com/page being blocked

To fix this requires to support exception filters for the document option. I will implement support for this, but of course the semantic of such filter in uBO will be completely different than that of ABP -- where the document option means "disable all filters for the document".

Does strict blocking syntax support some kind of string matching?
Edit: It supports wildcard * and seperator ^ but not regex
||example.com/_foo$document
||example.com/_bar^$document

It's just a filter option on whatever is a valid ABP-compatible filter syntax.
