hyprbars: buttons visible but not responding to clicks on Hyprland 0.54.2

## Description Hyprbars buttons are rendered correctly and visible in the title bar, but clicking on them does nothing — no command is executed. ## Steps to reproduce 1. Install hyprbars via `hyprpm` 2. Configure buttons in `hyprland.conf`: ```ini plugin { hyprbars { bar_height = 20 bar_buttons_alignment = right bar_button_size = 14 bar_precedence_over_border = true hyprbars-button = rgb(ff5555), 14, X, notify-send "test" "clicked" hyprbars-button = rgb(ffb86c), 14, F, hyprctl dispatch fullscreen 0 hyprbars-button = rgb(50fa7b), 14, T, hyprctl dispatch togglefloating } } ``` 3. Reload Hyprland 4. Click on any button in the title bar ## Expected behavior The command associated with the button is executed. ## Actual behavior Nothing happens. No notification, no command output. Even `notify-send` does not fire. ## Additional notes - `hyprctl plugins list` confirms the plugin is loaded correctly. - Tested with ASCII icons and Nerd Font glyphs — same result. ## Environment - Hyprland: 0.54.2 - hyprbars: installed via hyprpm from hyprwm/hyprland-plugins
