Toolbar icon incorrectly shown as paused when adblocking is active
(This is a copy of adblockinc/ext/adblock/adblock#285)
Steps to reproduce
- Install ABP
- Open options page
- Add custom filter
- Navigate to: https://testpages.adblockplus.org/en/filters/blocking
The toolbar icon is grey, as if the page was allowlisted.
Toolbar icon should be red.
