Remarks
The following arrays are used to handle property changes during a state. Because we can't store any stateful data here we can't know which emitter is ours. The best metric we have is an emitter on our Mesh Component with the same template and socket name we have defined. Because these can change at any time we need to track previous versions when we are in an editor build. Refactor when stateful data is possible, tracking our component instead.
