rv-each with multiple bindings

[tym-network]

I've been trying to display a list of items based on a model with data from another model. To avoid useless explanations, here is a fiddle: https://jsfiddle.net/y2kmy7aa/1/

As you can see, we lost the binding somehow for the colors. Even if you change the model, the view is not updated. Nevertheless, if you deselect the first item and reselect it, the color is updated.

Is this a normal behavior? Am i doing this wrong? Or is this an issue?
