Closing the last window in a workspace changes focus to the window/workspace under the cursor

[chrisr87]

I have a multi-monitor set up and when the last window is closed in a workspace, the focus switches to the window (or empty workspace) under the mouse cursor. Only way to stop this behavior from what I've tried is to set follow_mouse = 0 but that's not acceptable for me because I prefer to have follow_mouse = 2, which allows me to scroll a window without switching keyboard focus to it.

general {
    no_focus_fallback = true
}

input {
    follow_mouse = 2
    mouse_refocus = false
}

cursor {
    no_warps = true
}

I'm on the latest.

Thoughts?
