Bug Description

Steps to reproduce:

1. Open four windows, each using half of the screen:

                        ┌──C──╥──D──┐
      ┌──A──╥──B──┐     │┌──A─╨╥──B─┴┐
      │     ║     │     ││     ║     │
      │     ║     │     └┤     ║     │
      └─────╨─────┘      └─────╨─────┘
         2D view            3D view

2. Lower window A.

Expected behavior:

Window A is lowered:

                        ┌──A──╥──D──┐
      ┌──C──╥──B──┐     │┌──C─╨╥──B─┴┐
      │     ║     │     ││     ║     │
      │     ║     │     └┤     ║     │
      └─────╨─────┘      └─────╨─────┘
         2D view            3D view

Actual behavior:

Window A and window B are lowered:

                        ┌──A──╥──B──┐
      ┌──C──╥──D──┐     │┌──C─╨╥──D─┴┐
      │     ║     │     ││     ║     │
      │     ║     │     └┤     ║     │
      └─────╨─────┘      └─────╨─────┘
         2D view            3D view

Very nice. I fixed the whitespace by editing the description externally and replacing them with non-breaking spaces.

I am reminded of bug 1729461, although different. I also think there are similar bug reports elsewhere but can't find them.

Bug confirmed. But to lower a window with middle click you need to be logged into a Xorg session. It doesn't work in Wayland sessions (bug 1698083).

Revert "window: Raise and lower tile match in tandem"

Raising and lowering windows in tandem without a proper grouping
mechanism ended up being more annoying than functional.

This reverts commit e76a0f564c1e07e32fe857d0f8e5b723c3bbe57d.
