Why is a Safari page breaking iOS rendering?
This memory leaks is probably due to how 'WebKit’s JS Engine' works [safari webkit-javascript llvm]
and really looks like to be a virtual memory buffer-overflow, having a direct impact on the remaining RAM (shared and used also by iOS to store User Interface graphical elements)
Relatively to the piece of code: "[...]finding jQuery memory leaks is easy. Check the size of $.cache. If it’s too large, inspect it and see which entries stay and why. [...]" (http://javascript.info/tutorial/memory-leaks)
Let me expect that it is relative to this for loop :
for(var v in this.icons) { this.icons[v].css('z-index', + $icon.css('z-index') + 1); this.icons[v].css('transform', 'translate3d(' + iconX + 'px,' + (iconY + iconOffset) + 'px,' + '0px)'); iconOffset += 20; this.icons[v].appendTo($icon);}Assuming inspection is done, and also assuming the fact that you find the entries, you may want to clean the data manually with removeData()or you may use first $elem.detach() and then put $(elem).remove() in setTimeout.
