Rendering of focus control in preferences on Windows

[tobiasmelcher]

Hi SWT experts,

could you please help in answering the question when the focus control should be made visible by rendering the dotted outline around the control?

If I open the java editor preferences via the editor context menu, the focus control 'Text Editor' is directly visible on Windows and MacOS.
Java Editor Preferences on Windows (focus control visible):

Java Editor Preferences on MacOS (focus control visible):

If I open the properties via context menu from the console view, no focus control is visible on Windows. I have to press the ALT key to make the checkbox "Fixed with console" visible as focus control.

Console View Preferences on Windows (focus control not visible):

On MacOS, the focus control is immediately visible.

The MacOS behavior is for me consistent, the focus controls are always visible.
The Windows behavior irritates me, why is the focus control not always visible? It somehow depends which control is used. For the link control it is immediately visible, for the checkbox not.

Is the current behavior, correct? Is there an explanation for it?
