updateSize with google layers

[pgiraud]

I found that if you resize the map and switch to another google layer, it is not correctly positionned. I got a eye on it, and I can't figure out why.

To reproduce the bug, you can try the following code in your console in the spherical-mercator.html example :

map.div.style.width = 500; map.updateSize();

Then switch the baseLayer to the satellite.

I also tried with an older version of OpenLayers (revision 4950) and it behaves exactly the same.

note: I agree that this ticket needs a more explicit summary and description.
