📄 Description

In this case the main fix is

[window setCollectionBehavior:NSWindowCollectionBehaviorTransient];

In this case when deleteing the window we are instrucing macos display server to hide this window in mission control. This is the simplest solution I found and looks like work in all cases that are present in TheIDE. I didn't notice any drawbacks.
