Pop up: too close


@tomnod @HappyMapper : the last three mosques in Mosul I try to tag result in a pop up ‘too close’. When I tag near the mosque, the tag is placed normally. Is this a bug?

I had the problem in this polygon: http://www.tomnod.com/campaign/dghg_sitediscovery_2015_02/map/48ox6ey1uv

But also in polygons (two more mosques) straight up north, within a mille or so.
