It's exactly this reason why the roads should be at a single layer (except
the underpass) in a given vicinity, and the river set to one layer lower.
If you want to make all the roads layer=1, then feel free, but it's easier
to make the river layer=-1.
It's not a bug. The data is wrong. No renderer could reasonably be asked to
make sense of that mess.
