I believe it is honoring that too. It will check and requestFocus to `selectInitialValue(op)` initialValue and then fallback to `initialFocusComponent` if it is not set..


Object paneInitVal = op.getInitialValue();
                // must be from pane because BasicOptionPane
                // sets intialFocusComponent to the default button
                if (paneInitVal != null) {
                    if (paneInitVal instanceof JComponent) {
                        // if JOptionPane initialValue is a JComponent
                        ((JComponent) paneInitVal).requestFocus();
                    } else if (initialFocusComponent != null) {
                        // else custom option button gets
                        // the focus if available
                        initialFocusComponent.requestFocus();
