Jquery UI dialog vs datepicker

Hi.

I have the following code http://pastebin.com/raw/CZd3FsPm.

We are opening ui dialog with one input in it and attaching a datepicker.

It works like charm except in IE11 where it doesn't close on date selection. When a user clicks any date the datepicker hides itself and then immediately restores.

I've found the problem in these lines of code of jquery ui:

		if ( !this.document.data( "ui-dialog-overlays" ) ) {

			// Prevent use of anchors and inputs
			// Using _on() for an event handler shared across many instances is
			// safe because the dialogs stack and must be closed in reverse order
			this._on( this.document, {
				focusin: function( event ) {
					if ( isOpening ) {
						return;
					}

					if ( !this._allowInteraction( event ) ) {
						event.preventDefault();
						this._trackingInstances()[ 0 ]._focusTabbable();
					}
				}
			});
		}

_focusTabbable focuses back on input and datepicker reopens.
