This bug is perhaps not reproducable every time. I would appreciate if someone
else would have a look at this well.

When I scroll in the given HTML (where an SVG map is embedded, which has a png
image embedded) and I scroll as far as down that the SVG file is still partly
visible and then I scroll up again, parts of the relief aren't repainted. See
screenshot here:

It seems like the vector part of the map is correctly repainted, but the raster
part isn't.

Thank you for having a look at the issue!
