UIA - Aria-label of toggle button with menu truncated to first letter

[YanaLaurynovichTR]

Steps to reproduce:

1. Navigate to the example: https://stackblitz.com/edit/zal3su7x?file=src%2Fexample.tsx
2. Click "Toggle menu" button (aria-label="cite list")
3. Menu is opened / closed

Actual behavior:

NVDA announces only a first letter of aria-label

FluentUI React v9 - StackBlitz
c  button  expanded  
New  1 of 4
cite list
c  button  expanded  
cite list
c  button  collapsed 

Expected behavior:

NVDA announces "cite list button expanded"
Expecting this narration, because:

• Narrator reader announces it
• It is supported by ARIA button documentation https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/button_role

<button type="button" aria-haspopup="menu" id="menur3" class="fui-Button r1alrhcs" aria-label="cite list">Toggle menu</button>

Very similar to #17412
This is only an issue if you have set "Use UIA with Microsoft Edge and other Chromium based browsers when available" to "Yes" in NVDA's advanced settings

Thank you, @SaschaCowley, I have set "Use UIA with Microsoft Edge and other Chromium based browsers when available" to "No" in settings (it had default value) and labels for buttons have started to work as expected.

Changing to a p3 as this is only an issue with an advanced setting changed.
