This method relies on "SwingUtilities.layoutCompoundLabel" to generate alternative insets, so that's where I made my changes. Is this logic valid or should I contain my changes in AquaButtonUI?

Since this fix addresses `AquaButtonUI` only and we know for sure that other Look-and-Feels are also affected (Metal at least according to the comments in JBS and here), has anyone submitted a new bug for other LaFs?
