Prevent initial view.render when model.fetch is true

[yamsellem]

A glitch appears every time a view uses the loading helper.
— The view is rendered a first time.
— Then, the model is fetched and the view's loading attribute changes, so the the view is rendered a second time (showing/hiding things depending on the loading helper).
— Then, the fetch succeed or failed, so the view is rendered a third time.

The first render seems wrong to me. If a view has to fetch something, it should be hidden until the fetch has begin, right?

What is causing the first render here? A jsfiddle/jsbin would help debug this a bit. Generally we try to defer rendering of views as long as possible, so I suspect that the first operation is related to an insert or similar.
