I have configured my right mouse button to activate windows without passing the click ("Window Management"->"Window Behaviour"->"Window Actions" tab->"Inactive Inner Window Actions"->"Right Click"->"Activate"), and it works within the window contents, but if I right-click on titlebars or borders, I still get the popup menus.

I realise "Inner Window" suggests this is by design, but I do not see a way to configure identical behaviour on the "Titlebar Actions" tab either.

So when I want to remove focus from my active window, I have to pay careful attention *not* to click a decoration, otherwise I end up with an unwanted popup and focus doesn't change (so I need to try again).
