config.speaking_attribute not working properly with layeredimage

[kivik]

I use the config.speaking_attribute to define alternative images for speaking characters, and I've noticed that since I've converted all my characters into layered images, there's a problem with this feature.

My characters can successfully change from non-speaking to speaking version of their images, however they won't switch back from speaking to non-speaking when someone else speaks, so if multiple characters are on screen everybody ends up looking like they're speaking.

Normal images are unaffected by this.

This should be fixed in the 7.0.1 prerelease and the nightlies.
