Using filters makes batched textures on setTexturePriority method invisibles

[pacmanmulet]

Here an example of the problem: https://jsfiddle.net/eck2jdzp/

In the provided example, I create three sprites . After apply one or more filters to one of them, the sprites which texture was set on setTexturePriority method are not shown.

Thank you.
