Windows without decorations raised on click even when "raise on click" is off

Description

This bug refers to applications not using window decorations (title bar, borders). Two examples I can confirm this behaviour for are xfce4-terminal with View->Show Window Borders unchecked, and Chromium with "Use system title bar and borders" unchecked.

When xfwm4's "Raise on Click" setting is unchecked, the expected behaviour when clicking on a window that is behind another window is that it is not raised. For windows without decorations, the actual behaviour is that they are raised.

A workaround is to toggle the "Raise on Click" setting after the window is created. This affects the behaviour of currently existing windows, but new windows created after toggling the setting are still raised.

Note that versions of Chromium older than 53 contain a bug which raises their windows regardless of the window manager's "raise on click" setting. It was when testing the fix that I discovered this behaviour in xfwm4.

Version: 4.12.0
