The last viewed bookmarks folder does not stick

Hello, Since a few versions ago when you access a bookmark in a bookmarks subfolder and then, after viewing the web page, you go back to bookmarks, you are always back to the top bookmarks folder instead of the last selected one. Does anyone know if this is a bug or if it is intended? Before that, you were always brought back to the last viewed subfolder, which was perfect. Is there plan to have this behavior back? I really miss this! Thank you in advance Antoine
