/Steps to Reproduce:
1,Press Option+Space to summon the panel.
2,After completing the dialogue, click on another application. The panel loses focus and moves to the background.
3,Press Option+Space again. The panel cannot be recalled.
/Analysis:
-Why can it not be recalled?
The panel does not disappear; it only loses focus and is sent behind other windows. As a result, the Option+Space shortcut becomes ineffective.
-What is the core problem?
A user typically has many application windows open. To recall the panel, the user must manually hunt for its window among all others, click to regain focus, and bring it to the top. This process is exceptionally cumbersome and represents a design flaw.
-You've provided the Escape key to close the window. Why not close it after each use?
The user is not concerned with the technical state of the window (i.e., whether it is out of focus or closed). The user's only expectation is that pressing Option+Space will bring the panel to the foreground and make it active.
