[Popup] with on: "manual", attached to a "normal" element should not be shown above [Modal] (jsfiddle test case included)

[DamodarSojka]

(Instead of reading all this you can also just open the fiddle and it should be obvious what the issue is)

Steps

1. Attach popup (with on: "manual") to an element on the page.

2. Open Popup.

3. Popup is shown on the page.

4. Open Modal.

5. Modal is shown on the page, but the previously opened popup is shown above/on the same level the Modal is.

Expected Result

Popup to be shown below the modal (i.e. be dimmed by the Modal dimmer).

Actual Result

Popup is shown above the Modal.

Version

2.3.1 (my production) and (the version your example jsfiddle runs on)
