Windows 11 emoji panel/categories: NVDA says "clipboard history" twice when reviewing navigation menu items

[josephsl]

Hi,

Same UIA element selected issue as in #16346:

Steps to reproduce:

Prerequisite: Windows 11, clipboard should be empty (ideal; if not, clear clipboard history):

1. Open clipboard history (Windows+V).
2. Move to navigation menu. If clipboard entries exist, press Shift+Tab, otherwise focus moves to navigation menu when clipboard history opens.
3. Press left or right arrows to move through navigation menu items.

Actual behavior:

NVDA says "clipboard history" twice.

Expected behavior:

NVDA says "clipboard history" once.

Technical information

When moving through navigation menu (housing emoji, symbol, clipboard history, and other entries), gain focus event is fired when moving through entries. However, when clipboard history receives focus, both gain focus and UIA element selected events are fired. The solution is to detect gain focus event and vetoing element selected event if the former event is indeed ready to be handled. A fix is included in Windows App Essentials add-on and a pull request will be part of resolution for #16346 as both of these (and the next issue) deal with UIA element selected event handling for navigation menu items (Automation Id starts with "navigation-menu-item-").

Thanks.
