Mac: Regression: Projects Pane conext menu not dismissed after selecting 'Open With' editor

When the context menu is invoked with a mouse right-click on a file name in the Projects Pane and one of the editors selected from the 'Open With' submenu, only this submenu is dismissed, while the context menu itself remains on the screen. It takes either a mouse click or hitting Escape to dismiss it. It may be a related issue that when the 'Open With' submenu is activated but no item selected, the Escape key only removes the submenu, not the parent (context) menu, which takes another Escape hit to be removed.
