The clickable area around a google-map-marker is shifting/misplaced when text (or other content) is added before the map-div. It is working fine in chrome, ie etc. - only firefox seems to cause this problem (as far as I can see). When - in web-console - changing map-div's elementstyle from 'relative' to 'static' the problem is gone.
The code below is borrowed from googles map-examples - if I uncomment the lorem-text the map-markers clickable area is moving/misplaced. Any suggestions on how to solve the problem (if there is a problem - I might have missed something obvious):

UPDATE
This bug was handled in https://issuetracker.google.com/issues/35826867 and fixed in version 3.21 of API in September 2015.
Try changing the js src from v=3.exp to v=3
Specifying the version as v=3 ensure that you have the most recent release version. The current release version is 3.20. The problem arises with the experimental version, currently 3.21, which is the default default version if you do not explicitly specify a version using the v parameter.
