On my app I have a menu that worked fine until I upgraded react and react-dom.
After upgrading react and react-dom from version 16.14.0 to version 17.0.0- on menu click, the menu flashes-it opens and closes right away.

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

Current Behavior 😯

On menu click- the menu opens and closes right away, for some reason the ClickAwayListener is being fired.

Expected Behavior 🤔

On menu click- the menu should open, on click away it should close.

Steps to Reproduce 🕹

Steps:

1. Upgrade react and react-dom to v17.0.0
2. Click the menu
