Comment (by jacklenox):

 Isn't this the expected behaviour? `remove_all_filters()` removes all of
 the hooks from a filter, but not the filter itself.

 So, having run `remove_all_filters()`, if I ran `has_filter()` without a
 function to check, I'd still expect it to return `true`.

 Having said this, I'm actually a bit confused. I'm running trunk locally
 (up-to-date), and for me it's returning `false` under the circumstances
 above…
