Cannot move focused/visible space to another display

[mortimr]

Environment:

• macOS version: 26.4 (Build 25E246)
• yabai version: v7.1.17

Issue:
yabai -m space --display next silently fails when the target space is currently focused/visible. The command returns no error but the space doesn't move.
This also appears to be a macOS-level limitation, dragging the active space to another display via Mission Control no longer works either. Only inactive/unfocused spaces can be moved between displays.

Steps to reproduce:

1. Focus a space on display 1
2. Run yabai -m space --display 2
3. Space stays on display 1

Expected: Active space moves to display 2
Actual: Nothing happens, no error returned

Is this a known macOS Tahoe limitation, or a yabai bug?
