Menu key.currentKey undefined when deselecting

[melcherry98]

🐛 Bug Report

When deselecting a menu item initially set as selected using defaultSelectedKeys the key.currentKey value is undefined but if you deselect the same item after it is selected manually it returns the correct key.

🤔 Expected Behavior

I would expect key.currentKey value to be the key of the deselected item.

• deselect any menu item and view the value logged to the console.
