How to replicate the issue

1. Clone the project from github

git clone git@github.com:thewebmaster/material-ui-tooltip-on-flexlayout.git

2. Once cloned, go to the project directory and run npm install and then npm start and the project will start and open up your browser to http://localhost:3000/

3. Test material tooltip on Hover here... text. You should be able to confirm that the material tooltip at this state is working.

4. But if you open the Floatable Panel into a new window and hover over the Hover here... text, you'll see that the tooltip still appears from the original docked panel.
