Hey guys! 
I have a problem where browser on my mobile crashes when scrolled to the stereo panorama where I compare two images (https://bobro360.pl/portfolio/). It works fine on a desktop. It also works fine when displayed directly on mobile (https://bobro360.pl/pomost/) but when embeded it crashes on my iPhone 7 in both chrome and safari browsers. Doesn't crash on Sony Xperia Z5 in chrome browser. Other embeded tours work fine on iPhone. I tried different methods of embeding (iframe and wordpress plugin panopress) and they both crash browser.
Do you have any ideas why that might happen and what I can do about it? Or at least how can I see what's causing the problem? 
Thanks in advance.
