OverflowMenuV2: Should focus first item on open

[francinelucca]

Package

Browser

Chrome

Package version

1.23.1

React version

v17.0.2

Description

OverflowMenuV2 should immediately focus the first MenuItem after being opened, compare to OverflowMenu's behavior, which is correct.

Note: the fix for this should be at the Menu component level which is where this logic is abstracted and what OverflowMenuV2 is implementing under the hood

5. Notice the focus is shown correctly in the first MenuItem
