Tags/Window modules not loading, "river_status_manavger_v1 not advertised"

[neocow]

Describe the bug
It's a very similar bug to #1280 except the bar still runs and displays all the other elements and applies to the window module too.

To reproduce
Run waybar with the river/tags and river/window modules enabled in the the config.jsonc file.

{
    "moldules-left": [
        "river/tags",
        "river/window"
    ],
    "river/window": {
        "format": "{}"
    },
    "river/tags": {
        "num-tags": 10,
        "hide-vacant": false
    }
}

Expected behaviour
Assuming this isn't an issue on River's end, it should display the modules.

Screenshots
They don't seem to be applicable but I can provide them if necessary.

Environment

Additional context
The only other thing I can think that might be relevant, why I thought this could be an issue with river, is if I configured my init file in a way that would somehow lead to these conditions. I found surprisingly little documentation on how you're meant to do that if you're just handing everything off to a separate window manager.

I suspect all these labels were added because the debug output was with the full config file? As far as I can tell, only the "bug" label is relevant.
