Hi,

Follow-up to #14538 but won't show up for a while (Insider Preview feature at the moment):

Background:

As part of Windows 11 22H2 Moment 2 (under testing), redesigned taskbar and system tray will be made available to users, more so if using tablets such as two-in-one devices. At least taskbar can be navigated using mouse and/or touch, but the redesigned system tray overflow window cannot (at the moment).

Steps to reproduce:

Prerequisites: Windows 11 22H2 beta builds (one must be a Windows Insider to test this):

1. Install Windows 11 22H2 build 22623 or later (must be a Windows Insider subscribed to beta and/or dev channel).
2. Enable mouse tracking (NVDA+M) and follow mouse from review cursor settings panel.
3. Press Windows+B to move focus to system tray/show hidden icons button.
4. Press Space to activate it.
5. Use the mouse to navigate the overflow window.

Actual behavior:

No announcement from NVDA regarding overflow buttons.

Expected behavior:

NVDA announces overflow buttons when moving the mouse.
