MPRIS block: `dynamic-len` ignored

[LordMZTE]

The dynamic-len setting of the mpris block doesn't seem to be respected, the text length often going way beyond the set limit.

Version info

$ waybar --version
Waybar v0.10.4

To reproduce

1. Configure the MPRIS block with this config:

{
    "format": "{status_icon} {dynamic}",
    "interval": 5,
    "dynamic-len": 24,
    "dynamic-separators": " 󱓜 ",
    "dynamic-order": [
        "title",
        "artist",
        "position",
        "length"
    ],
    "dynamic-importance-order": [
        "position",
        "length",
        "artist",
        "album"
    ],
    "status-icons": {
        "playing": "󰏤",
        "paused": "󰐊",
        "stopped": "󰓛"
    }
}

2. Play content with a long title.
3. Observe that the length (here: 24 characters) is exceeded.

Screenshots

Here, we see the MPRIS block with the above configuration displaying content over 24 characters.
