actions object does not register listeners

[repixey]

It looks like this is not currently happening, for example:

{
  "disk": {
    "interval": 3,
    "tooltip": true,
    "tooltip-format": "{used} used out of {total} on {path} ({percentage_used}%)",
    "format": "{used}",
    "unit": "GB",
    "path": "/",
    "actions": {
      "on-click": "nemo"
    }
  }
}

{
  "disk": {
    "interval": 3,
    "tooltip": true,
    "tooltip-format": "{used} used out of {total} on {path} ({percentage_used}%)",
    "format": "{used}",
    "unit": "GB",
    "path": "/",
    "on-click": "nemo"
  }
}

correctly opens it. Am I misunderstanding the logic for the "actions" object?

I also tried to run waybar --log-level trace but there are no logs for such things.
