Describe the bug
If a button has a long running command in on_click, it'll execute the command once, wait for it to close, them run the command again.

This is different from the behavior of other widgets, like labels with a command in on_left_click. In that case, the command will be executed again as soon as you click, regardless of if the previous instance is still running.

To Reproduce
Steps to reproduce the behavior:

Make a button with a command that'll take a long time (for example, launch an app)
Click on it
Click on it again while it does its thing (for example, while the app is open.) It'll do nothing.
Once the first execution ends, the second will being

Expected behavior
I'd expect it to run its command immediately each time it's clicked, regardless of if the previous execution is finished or not.

System information:

Distro: NixOS (unstable)
Compositor: Hyprland
Ironbar version: 0.16.1

Configuration

Minimal Config to reproduce

[[start]]
type = "custom"

[[start.bar]]
type = "button"
label = "launch terminal"
on_click = "!xdg-terminal-exec"
