Corrupts iOS page cache (aka back-forward button cache)

[tengelin]

Turns out that adding a listener to devicemotion event corrupts page cache, aka back-forward button cache. Easily tested by adding below script to page and browsing between pages using back button.
window.onpageshow = function(e) {
console.log(e.persisted);
};
