Is this a bug in the renderer or in the data: Look at Moscow in the humantarian renderer a.k.a. layer

Isn't there some problem with data in the area, like gap in the rivebank or in the lake?

All other renderers show the area correctly. This is possibly related to administrative borders rendering.
