Subject: QStyleSheetStyle: Don't interfere with QFontDialog

The sample lineedit in Qt's own font dialog shouldn't have its font
affected by stylesheets.
Not only does this hampers the ability to preview the font, it actually
overrides the font selection as that one is taken directly from the
widget.

Task-number: QTBUG-41513
Change-Id: I11d0bef8c7bf7bdae4cc08b6b9276d0fc14a75fb
