"Open in New Window" Not Working in v38

Hi, just updated to v38. When I show a list of draft after a quick search, I don’t have the ability to right-click on a draft and choose “Open in New Window” any more. When I right-click, nothing happens. Previously, a context menu would appear with options (open in new window, move to inbox/archive/trash, flag, unflag, copy> etc)

Anyone else experiencing this?
