Apparent bug with google maps v3 and Safari 5 antialiasing on os x

I've found what appears to be a bug with the Google Maps V3 API and Safari 5 on OS X.

It's quite simple really. As soon as the map loads it kills the antialiasing on any positioned elements (relative, absolute of fixe开发者_JAVA技巧d).

Here is a jsFiddle http://jsfiddle.net/fuzzyd/XXhky/3/ so you can try it for yourself.

Does anyone have any ideas about how I could possibly sort this?

Thanks

EDIT: This seems to be fixed in the most recent version of Safari and/or Google Maps.

EDIT2: Or maybe not.
