Windows 11 emoji panel: prevent speech repetition while browsing panel items (#18237)
Fixes #18236
Summary of the issue:
NVDA repeats Windows 11 emoji panel items twice while browsing them.
Description of user facing changes:
NVDA will no longer speak Windows 11 emoji panel items twice.
Description of developer facing changes:
NVDA will call nextHandler() when handling UIA element selected event while focused on the emoji panel.
Description of development approach:
When handling element selected event, call nextHandler() if focused on the emoji panel. This also improves element selected event performance as emoji panel item selection announcement will not involve traversing the event handler to the end.
