If a desktop has a single window in it and when the desktop layout is changed to float, this window performs weird

[rockyzhang24]

yabai version: v3.2.1 (the latest master)
macOS version: 10.15.5

To reproduce the issue:
In an empty desktop (workspace), open a single random window say a kitty window. Then we change the layout of this desktop to float by yabai -m space --layout float.

1. This window size cannot be resized by yabai -m window --resize ...
2. This window cannot be moved by yabai -m window --move ...
3. yabai -m window --grid ... does not work either
4. Furthermore, open another random window say Notes.app, and then we change the layout of this desktop back to bsp by yabai -m space --layout bsp. We can see that the kitty window and the Notes.app window are not tiled and instead the Notes.app window will fill the whole screen above the kitty window.

HOWEVER, if initially in an empty desktop we open two or more windows before we change the layout to float, all the windows perform well. I can resize, move any window (i.e., issue 1, 2, 3 don't exist). Also, like 4 above, if I open another random window and then I change the layout back to bsp, all the windows will be tiled.

Thank you very much.
