Summary:
The status bar area of the menu bar is not updated after the  cog displayed in the menu bar status area when a NSAppleScript is executed in the background disappears, leaving a gap until the user switches apps or uses Exposé functions.

Steps to Reproduce:
1. Open Automator
2. Choose to create a service
3. Insert a single “Run AppleScript” component
4. paste in the following example code:

tell application "Mail"
	my markMailboxAsRead(get selected mailboxes of message viewer 1)
end tell

on markMailboxAsRead(targetMailbox)
	tell application "Mail"
		repeat with theMailbox in targetMailbox
			set unreadMessages to (every message of theMailbox whose read status is false)
			repeat with aMessage in unreadMessages
				set read status of aMessage to true
			end repeat
			repeat with subMailbox in every mailbox of theMailbox
				my markMailboxAsRead(subMailbox)
			end repeat
		end repeat
	end tell
end markMailboxAsRead

5. save the service
6. open System Preferences → Keyboard → Shortcuts
7. assign a hotkey to the newly created service (ex. Ctrl-Cmd-u)
8. close System Preferences
9. open Mail.app
10. navigate to a mail folder
11. watch the status bar area of the menu bar
12. press the hotkey defined in 7.

Expected Results:
The script cog appears in the status area, spins, then disappears, leaving the status area in its previous state.

Actual Results:
The script cog appears in the status area, spins, then disappears, leaving a gap in the status area at its position.

Notes:
Behavior is not dependent on target application, script code or script host application (it’s identical with NSAppleScript based Alfred workflows, for instance).
