P: Lr 8.4 after restoring a deleted image, focus for arrow keys isn't retained in previous albums.

Ver8.4

消去済み画像を復元したのち、最近の項目に戻った時、左右の矢印が機能しなくなるバグが発生。

一度アプリを閉じ再度開くと治るが、根本解決にはなっていない。

Hey, @こき. Welcome to the Lightroom Community. Thank you for the report. 

I can recreate this, and I'll share it with the team for review. For now, it just required a few extra clicks to get back to work: Click on any other image in the filmstrip, click on the Grid view icon or press G on the keyboard > click on any image in the grid, and the arrows continued to function. 

Let me know if this helps.
