JetBrains: Leave popup open when focus leaves the IDE

Created by: vdavid

Context

Currently, when the "Find on Sourcegraph" popup is open and one focuses away from the IDE with Cmd+Tab on a Mac, the popup disappears. The "Find in Files" native popup remains open on Cmd+Tab.

Problem

This behavior somehow makes the popup feel awkward and unusual for the IDE. This is something that I (David) as a long-time JetBrains user notice a lot and has a strong negative impact on my experience.

Solution

Keep the popup open until the user closes it with Esc, Alt+Enter, or clicking away from it inside the IDE.
