(SOLVED) Error in ScrollArea to return from .html in fullscreen with Chrome 47 Android

Hi, my project is formed for 3 .html groups:
1) Plain Panorama to splash (index.html)
2) Plain Panorama Map to link to many VTOURs (p1.html). This map have a bottom bar scroollArea to access a code to create hotspot in the map. This hotspot links to VTOURs. (3)
3) Standart VTour ganerated from droplet

The problem occurs when you set FULLSCREEN any VTOUR (3)... Then to comeback to map, the ScroollArea is not visble, maybe it is in any bottom zone, but is not possible to see it. This error break the navigation bt the Map and vtour.

Any idea?
Thanks in advanced, best regards

Fernando

Note: Tested in Chrome 47 Android fullscreen in vtour

Edit: The solution was first to turn off fullscreen in exit buttom:
1) set(fullscreen, false);
and after then:
2) jscall('window.history.go(-1)');
