flickering caused by aurelia rendering content before clearing the old

[wzrdtales]

We noticed that there is some flickering while navigating

So we recorded it

In specifically this frame

You can see what is happening aurelia actually renders the content of au-viewport before clearing the old.

This is a child router constellation and the navigation simply uses the load attribute to call the other child route.

not really a question, I guess its a bug @bigopon That is definitely not a behavior that is expected

This behavior is because the router is having rendering sequence add first then remove existing. We can change that to remove existing and then add. Maybe @jwx will comment more.
