window switcher menus are not visible to AT-SPI2
The menus that appear when right-clicking on a button in the window switcher are not visible to AT-SPI2.
Steps to reproduce:
- Open Accerciser.
- Expand the xfce4-panel application.
- Right-click on a button in the window switcher.
A window should appear as a child of the xfce4-panel application, containing the menu, but there is no visible change in the tree in Accerciser. This makes it impossible to tell through AT-SPI2 that the menu is open.
