[macOS] No method to invoke context menu via keyboard for focused toolbar button

[acornestean]

Description:
Checking keyboard navigation revealed that there is no method to invoke the right click context menu of the toolbar button if it was focused via keyboard and the cursor is not on the button.

There is a method to enable the invocation of the right click context menu via the “Enable Alternate Pointer Actions” from the Pointer Control accessibility settings, however this requires the mouse pointer be on the toolbar button as the context menu is invoked at the pointer position.

Note that this is not an actual issue with the extension, but a limitation of the OS, however it hinders keyboard navigation of the extension menus.
