When Opera has one regular window open in fullscreen and one or more private windows in full-screen, closing a private window with "command + w" will cause Opera to quit.
Opera version 57.0.3098.116, running on macOS Mojave.
Steps to replicate:
- Open a new window in Opera (may or may not have multiple tabs), visit some websites, and move this window to fullscreen.
- Open a new private window in Opera (with or without VPN turned on), visit some websites, and move this window to fullscreen.
- Navigate to the private fullscreen window and enter "command + w" to close the window.
- Opera quits.
Any suggestions on what could be going on?
