Incorrect extended CSS rule causes that JS rules don't work

[AdamWr]

Steps to reproduce

1. Add these rules: example.org#?#body > div[class="":has(h1) example.org#%#alert(1);
2. Go here - http://example.org/

Expected behavior

I think that JS rules should still work.

Actual behavior

JS rules don't work.

The real case is here - https://github.com/AdguardTeam/AdguardFilters/issues/41420 It seems that this rule:

cosmopolitan.lt,moteris.lt,panele.lt,manonamai.lt,tavovaikas.lt,delfi.lt#?#a[href="javascript:void(-1);":-abp-has(a[title="[x] Uždaryti"])

from EasyList Lithuania is inccorect and causes that JS rules don't work.

It seems that some rules still cause that problem. I'm not sure if I should open new issue in this repo or maybe create issue in ExtendedCSS repo - https://github.com/AdguardTeam/ExtendedCss/issues, so I'm writing comment here.

Steps to reproduce

1. Add these rules:

   example.org#?#body:has(div),
   example.org#%#alert(1);

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

Expected behavior

JS rules should still work.

Actual behavior

JS rules don't work.
