maps page never stops loading

Noticed some bug on pages with a single map (not a mashup). Page never stops loading in case of receiving some files for map. If page is reloaded for a few times – loading completes. Example: http://exploreua.com/en/halych-castle
It is a very bad bug, cause a Lightbox nor the AdThis plugins can’t be loaded if map is loading. Need help!
