Merged containers' loading behavior

[Floriferous]

When merging multiple composers, I'd expect the loading component to start appearing when going through the first composer, and end when all the data has arrived, is this how it is handled? Also, would the component, if provided, animate continuously ?

To illustrate, what is the difference, if any, between these 3 approaches:

export default merge(
    compose(dataLoader1),
    compose(dataLoader2),
    compose(dataLoader3, optionsWithLoadingComponent),
)(UIComponent);

export default merge(
    compose(dataLoader1, optionsWithLoadingComponent),
    compose(dataLoader2),
    compose(dataLoader3),
)(UIComponent);

export default merge(
    compose(dataLoader1, optionsWithLoadingComponent),
    compose(dataLoader2, optionsWithLoadingComponent),
    compose(dataLoader3, optionsWithLoadingComponent),
)(UIComponent);
