Overzealous ABP filtering: `||` needs to match beginning of domain name

[gorhill]

Currently, || is parsed as if || was not present. For instance this overzealous ABP filtering breaks http://lifehacker.com/, because the CSS file http://c.kinja-static.com/assets/stylesheets/tiger-658d9988e2c6168ab0470b1da909a736.css is blocked through ABP filter ||a-static.com^$third-party in EasyList.

As per "Writing ABP filters": "two pipe symbols in front of the filter [...] makes sure the filter matches at the beginning of the domain name"

Meanwhile, workaround is to disable ABP filtering for lifehacker.com scope.
