[BUG]: move/resize of an unmanaged window affects workspace focus

[raggi]

Describe the bug
Create an unmanaged window, say a layered window from some random program - for me a whatsapp window will do.

When that window is initially focused, there's no border window active, as there's no managed window focused.

If I move the whatsapp window though, a managed window underneath the mouse (and whatsapp window) at the time I stop moving the window is "focused" within the workspace, resulting in the border window also unhiding itself, and making it appear as if the managed window underneath is now focused - but it is not!

To Reproduce
Steps to reproduce the behavior:

1. Create several managed windows.
2. Create an unmanaged window.
3. Click and drag the managed window over the top of a managed window.
4. See the managed window get "focused" internally, and the border window moving.

Expected behavior
Moves of unmanaged windows should not affect any focus information for managed windows, and should not cause the border window state to change (it should already be disabled, and remain disabled).
