window.focus is triggered twice on Safari but only once in Firefox and Chrome

[mircealungu]

must find a way to debounce this.

somebody else discovered this behavior long time ago: facebook/react#10871

seems to still be there.

Howdy,

I had a similar issue with the following code

items[i].onfocusout = function () {}

The focusout event is called twice only in Safari. My server would receive two requests and the UI would show a notifications after each request.

However, I updated the code to using the addEventListener function and it resolved my issue. Now Safari only triggers once.

items[i].addEventListener("focusout", function() {});
