emojier: quit on copy
After you select an emoji, what's the thing you're going to want to do next? Paste it! But to do this, you have to get rid of the window. That's a manual step that slows you down.
Instead, let's quit automatically after copying an emoji. It will show a system notification that shows what happened after the app quit, so you don't end up disoriented.
BUG: 467662 FIXED-IN: 6.3.0
