hyprland/workspaces: duplicated workspaces #4307

I have something like this in my hyprland config:

workspace = name:code, persistent:true
workspace = name:web, persistent:true
...

So that I can do this in my Waybar config.jsonc:

"hyprland/workspaces": {
    "format": "{icon}",
    "sort-by": "name",
    "format-icons": {
        "code": "C",
        "web": "W",
        "1": "1",
        "2": "2",
        "3": "3",
        "4": "4",
        "5": "5",
        "6": "6",
        "7": "7",
        "8": "8",
        "9": "9",
        "10": "0"
    }
}

But what I get is:

In other words: duplicated workspaces. However, only one of them actually works.

The button styles defined in style.css (like #workspaces button.visible, #workspaces button.urgent, etc.) only apply to the one on the left. I thought it might be an issue with the workspace names, and I found that adding this does remove the duplication:

"hyprland/workspaces": {
    "ignore-workspaces": [
        "^[a-zA-Z]+$"
    ],
    ...
}

But this ends up removing the correct one. That is, the remaining one does not have any of the expected styles such as #workspaces button.visible or #workspaces button.urgent.

Summary:

• When creating named and persistent workspaces, Waybar shows duplicates.
• One of them works properly and seems to not be the one associated with a numeric ID (or something like name:code instead of code)
• The other one lacks styling and functionality (like visibility or urgency).
