Unable to get property 'nodeName' of undefined or null reference

[H2Os]

Very niche issue which appears to be limited to IE:

JavaScript runtime error: Unable to get property 'nodeName' of undefined or null reference

When displaying a popup using .popup('show') the error above is thrown in _safelyBlur, called from _openPrerequisitesComplete when this.document[ 0 ].activeElement is null.

Run in IE with the F11 dev tools open (also occurs in Visual Studio when in debug mode).

This will be fixed when #7927 lands.

Is this supposed to be fixed? Because I'm still experiencing the mentioned issue.

I think it's due in 1.5 - in the meantime, I have been using this workaround:

//Fix for nodeName undefined error on IE
$.widget("mobile.popup", $.mobile.popup, {
    _safelyBlur: function (currentElement) {
        try {
            this._super();
        } catch (ex) {
        }
    }
});

Thanks, I'll try that!

Still getting this error in IE 10, but only on one of my several popups.
Good thing the fix works, thank you.
