Middle click on modal causes overlay to ignore next click

[ericman314]

Summary:

When the modal is open, middle clicking anywhere on the modal content causes the next click, if on the overlay, to be ignored.

Steps to reproduce:

1. Run using npm start
2. Click the button to open the modal
3. Middle click or middle drag on the modal content
4. Click on the overlay
5. The modal does not close
6. Click again on the overlay
7. The modal does close

Expected behavior:

The modal should close the first time when clicking on the overlay

Additional notes:

The default example on code sandbox does not exhibit this behavior. I tried to create my example on code sandbox but the site wasn't working for me for some reason.
