Hi,
I'm using the latest version (23.2.0) of elastic UI and was trying the "Small Flyout, own Focus" demo in my own dev environment.
When I click the button, i realize the overlay mask stays on even though the drawer has closed.
On inspecting the browser console, i realize there's two EuiOverLayMask component created when the drawer is open. When the drawer is closed, there's still one remaining in the DOM, causing the issue.
