Empty “ghost” Brave windows on Mac OS X

Description of the issue:
This issue is similar this bug. I created couple apps (Menu -> Install ). And if I open the applications after a while, empty windows appear. This windows don’t close after close app, and not present only after restart brave.

How can this issue be reproduced?

  1. Create app from any site (for example twitter)
  2. Open this app and brave

Expected result:
The empty windows do not get created.
