Unable to active window from other application previously behind after closing browser window

[serenvillwock]

Describe the bug
After closing a Cyberduck window, the area where the window was becomes non-clickable until you click an area outside where the window was.

To Reproduce
Steps to reproduce the behavior:

1. Click on Cyberduck 2 app in the dock to open a window
2. Click on something within the Cyberduck app, like the menu bar
3. Click on the red X to close the window
4. Click on the desktop or another window behind where the Cyberduck window was on the screen
5. The click does not register and the Cyberduck app stays open as if the window is still there
6. Quit Cyberduck or click to an area outside where the window was to restore function

Expected behavior
After the Cyberduck window is closed, you should be able to click on items behind where the window was.

I can reproduce. This seems to apply for the Preferences window as well.

Looks like we can workaround by setting NSWindowCollectionBehaviorTransient on the window.
