QCommandLinkButton doesn't like large icons or newlines in the description.

QCommandLinkButtons have an unexpected behavior in layouts:

1) If a large icon is used (say 64x64), the icon is often clipped along the bottom, even when the icon size has been explicitly set with setIconSize().

2) If the description text is rather long, and includes a Newline char, it will often clip the text when the QCommandLinkButton is resized (try increasing and decreasing the size a few times).
