If we want this behaviour, why not just put a Focus widget around the route?

...but I'm not convinced we want this behaviour. It's not what happens on Windows and macOS as far as I can tell.

I think this is just something we want on Web, and on Web the behaviour is just that the root of the tree is itself focusable, no need to check whether a tap would have focused a node and all that.
