Is there a reason we need to have the label to be implicitWidth?
Right now, we get a binding loop on width: Math.min(label.implicitWidth + units.smallSpacing, parent.width - units.smallSpacing * 4).

Also, the icon uses units.smallSpacing for the leftMargin, while the label currently uses 2 * units.smallSpacing for the leftMargin. I've changed it so they're both the same width since width is more important for the label.
