Canvas computation order

Does anyone what order the canvas computes components? is it location/stream start based?

example, i have (3) streams, which one is computed first?

there may be a better way of doing this but my specific case I’m defining a sticky dictionary that is a single component that i need to initialize when the snippet is brought onto the canvas. several components will read the initialized value.

in my experience whichever plopped onto the canvas first gets computed first
