Do you also use Spiderfier and Clusterer?
The fitBounds function still doesn’t seem to work and centers my map somewhere along the equator, so I believe it’s the same in your case?
I will probably find a way with a different map script, like Leaflet or Open Street Map, because Google Maps doesn’t seem to recognize this issue and cannot recreate it (I asked for support there too).
Let me know, if you find a different solution 😉
