Google Map Test

The funny thing is that when I place the same map within [[collapsible]] block it shows my path as a small red dot in the upper-left corner of the map:

The code I'm using looks like this:

@@[[include google-map2-test]]@@
<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src=";hl=pl&amp;geocode=&amp;;ie=UTF8&amp;t=h&amp;ll=52.214759,-0.074752&amp;spn=0.004086,0.012074&amp;output=embed&amp;s=AARTsJpulB7m5Spt58-ayEg9w5FtIObPTw"></iframe><br /><small><a href=";hl=pl&amp;geocode=&amp;;ie=UTF8&amp;t=h&amp;ll=52.214759,-0.074752&amp;spn=0.004086,0.012074&amp;source=embed" style="color:#0000FF;text-align:left">Wyświetl większą mapę</a></small>

I can embed Google maps showing my *.kmz without any problem:

Wyświetl większą mapę

and was generated by itself, so…
Any ideas? It's better to ask first before saying it's a wikidot bug :)

standard - live "_template" used without any tricks and layout changes…
