Mac: "Select All" within ListView/TreeView is handled differently depending on the useSystemMenuBar value

Lets define a "Select All" menu item with CTL + A / CMD + A accelerators.
When calling "Select All" while a ListView or a TreeView is focused, we get different behavior depending on the useSystemMenuBar value :
- if we do use the system menu bar (Mac OS), the menu item onAction method is invoked
- if we do not use the system menu bar (windows), the menu item onAction method is not invoked

The behavior should be the same.

Simple test case to reproduce.
