```
3. Wait for filters to convert
4. Open `https://www.reddit.com/r/AskReddit/comments/1vzcoet/what_antagonist_from_a_video_game_is_impossible/` in Safari

### Expected Behavior

The sparkling AI button in the header is hidden by rule `www.reddit.com###answers-nav-button`

### Actual Behavior

The sparkling AI button is not hidden. The presence of the uBO-styled `:remove-attr()` rule breaks the `#answers-nav-button` filter.
