"Text style" reset button for frame text is active even when no changes have been made

2.0.3 / Win 7 / 8 Pro.

Open an example score – Marc Sabatella's "Reunion" for example. Click on any text in the title frame. The "Text style" reset button in the Inspector is active (although no changes have been made in the current session).

But if you click on any other non-frame text objects, the same reset button is inactive (as expected).
