[Menu] iOS Voiceover focus trapped after selecting a menuItem

• [ X ] The issue is present in the latest release.
• [ X ] I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

With voiceover enabled on iOS, when the user opens a menu and selects an option, the menu closes as expected however the focus gets trapped on the selected menu item even though the menu has closed.

Expected Behavior 🤔

Once a user opens and selects a menuItem, the menu should close and focus should go back to the Menu Button

Steps to Reproduce 🕹

Steps:

With voiceover enabled on iOS:

1. Navigate to Icon Menu Button
2. Double-tap to open the menu
3. Swipe to Select an option from the menu
4. Notice that the menu closes and the focus gets stuck on the selected menu item even though the menu is closed

Context 🔦

It would be great if the focus would shift back to the Menu button.

Your Environment 🌎

Reproduce the behavior in the linked CodeSandbox with iOS VoiceOver, then trace the Menu and MenuItem focus handling when the menu closes. Done means the menu closes after selection and VoiceOver focus returns to the Menu Button rather than remaining on the selected item.
