Support for the data-order attribute was added to the navigation here. However, this is not yet supported in Dev Tools. Furthermore, it seems that manually adding something like data-order=10000 has no effect on the order of the button.
I believe the navigation button is currently meant to always be the last button? So, this would probably need amended in addition to adding the actual data-order value.
