Method to Detect Always-Active

[landoncrabtree]

        var i = 0;
        var blur = false;

        window.onfocus = function (ev) {
            if (i > 0 && !blur) {
                console.log("onFocus() but never called onBlur()")
            } else {
                i++;
                console.log("onFocus: tab is active");
            }
        };

        window.onblur = function (ev) {
            blur = true;
            console.log("onBlur: tab is inactive");
        };

This Javascript can detect Always-Active. If onFocus is called, but onBlur was not, then wouldn't that imply something fishy is going on and that the user did indeed lose focus of the window?

Closing as fixed.
