Steps to reproduce:

1. Install most recent Teams
2. Focus an incoming message in a chat or team channel.

Actual behavior:

NVDA reads the incoming message.

Expected behavior:

NVDA starts reading the incoming message, but this is suppressed by a menu getting focus. This is the menu that allows you to pick a reaction for a message (e.g. like). A focus triggers this menu. It doesn't strictly gain focus, however NVDA"s handling of the menuStart event redirects focus to it.
