Quick's Text doesn't render connected Arabic characters properly if RichText elements are used

Qml will disconnect Arabic characters into stand alone characters if RichText elements are used to set styling for the text.

Example QML:

Text {

      id: resultTxt text: "بِّسْمِ اللَّـهِ ا<span style=\"color:blue\">ل</span>رَّحْمَـٰنِ الرَّحِيمِ"

     }

as opposed to :

Text { id: resultTxt text: "بِّسْمِ اللَّـهِ الرَّحْمَـٰنِ الرَّحِيمِ"}

For a comparison, the font was rendered correctly on Firefox browser, as shown in the attachment. Also attached is the rendering of the first Qml text output with RichText elements.
