title: IOS 10.3.3 Iphone Safari beforeunload, unload, pagehide wont work
body: <p>I'm trying to catch <em>beforeunload</em>, <em>unload</em>, <em>pagehide</em> events on iPhone Safari (602.1) IOS 10.3.3. But it seems that on iPhone these events don't fire, and the funny part is that on iPad which has same versions of browser and IOS, the events <strong>do</strong> fire. The only difference that I noticed was that iPad gives you the tab option but iPhone doesn't. Is there any way to catch these events on iPhone IOS 10.3.3? </p>
  
  <p>Note: These events do fire on iPhone IOS 8.4.1.</p>
