If there is an OS behaviour change, it's presumably down to the cascade of events from one child of a parent window to another, when one of them doesn't handle a key press.
That made it click: The key equivalent is in a context menu, context menus are outside the regular view hierarchy, so that is what is causing the problem.
I have pushed v2.0.19 which contains a fix for this. Hold option (⌥) when checking for new build. Though it will be promoted to regular release shortly, given the severity.
I am terrible sorry for anyone who has been affected by this!
