After a window with focus is minimized, yabai still reports that the window has focus.

[I-Want-ToBelieve]

You can easily reproduce this issue using the following script

# Get the current window's ID and has-focus attribute
window_info=$(yabai -m query --windows --window)
window_id=$(echo "$window_info" | jq '.id')
window_focus=$(echo "$window_info" | jq '."has-focus"')

# Print the window's ID and has-focus attribute
echo "Window ID: $window_id"
echo "Has Focus: $window_focus"

# Minimize the window using the yabai command
yabai -m window "$window_id" --minimize

# Wait for 1.5 seconds
sleep 1.5

# Query the window's has-focus attribute
window_focus_after=$(yabai -m query --windows --window "$window_id" | jq '."has-focus"')

# Print the window's has-focus attribute after minimizing
echo "Has Focus After Minimize: $window_focus_after"

❯ nix-shell -p jq

[nix-shell:~]$ # Get the current window's ID and has-focus attribute
window_info=$(yabai -m query --windows --window)
window_id=$(echo "$window_info" | jq '.id')
window_focus=$(echo "$window_info" | jq '."has-focus"')

# Print the window's ID and has-focus attribute
echo "Window ID: $window_id"
echo "Has Focus: $window_focus"

# Minimize the window using the yabai command
yabai -m window "$window_id" --minimize

# Wait for 1.5 seconds
sleep 1.5

# Query the window's has-focus attribute
window_focus_after=$(yabai -m query --windows --window "$window_id" | jq '."has-focus"')

# Print the window's has-focus attribute after minimizing
echo "Has Focus After Minimize: $window_focus_after"
Window ID: 979
Has Focus: true
Has Focus After Minimize: true

[nix-shell:~]$

yabai caches the id of the active window, and the cache is only updated when macOS reports that a new window has become the key window. I guess if you minimize the only available window, macOS focuses the "Finder desktop window" and we need to catch that somehow.

It seems that this is also one of the quirks of macos.

If yabai has nothing to do here, then this issue can be closed
