Umbrellas...move up the side of buildings!

[i-am-pam]

I notice that when walking from foreground to background in the rain, pedestrians' umbrellas appear to move up the side of the building that they are walking alongside, instead of being obscured by the building.

I also have two separate unconnected comments about dog-walking and ambulances.

Yes, I know about this problem.
This is one of the small problems we need to take care about in the long run.
I hope one day this and others to be fixed.
