Comment:

 #21169 does not resolve this issue. The problem here is that the if we've
 got recursive calls on apply_filters, when we return one level up, the
 array pointer might not be in the expected position(because of the reset
 and next/each over the same array). That'd require to make a copy of
 $wp_filter[ $tag ], and iterate over the copy, to be fixed.
