[Bug]: Cava decolouration

[insideoutsidein]

Current Behavior

When using cava as a command as a custom widget, it doesn't work for me. Using bash -lic cava does, however. The issue is when cava is no longer the active terminal, the colour changes quite drastically.

Expected Behavior

I don't expect cava to change colour so drastically, and I'm not sure if that's a cava issue or a wave issue, or some incompatibility

Steps To Reproduce

1. Use waveterm
2. Add this widget:

    "cava": {
        "icon": "chart-simple",
        "label": "cava",
        "blockdef": {
            "meta": {
                "view": "term",
                "controller": "cmd",
                "cmd": "bash -lic cava"
            }
        }
    }

3. Add this into your cava config:

[color]
# vertical rainbow gradient (bottom → top)
gradient           = 1
gradient_color_1   = '#8B00FF'   # violet (lowest)
gradient_color_2   = '#0000FF'   # blue
gradient_color_3   = '#00FFFF'   # cyan
gradient_color_4   = '#00FF00'   # green
gradient_color_5   = '#FFFF00'   # yellow
gradient_color_6   = '#FF7F00'   # orange
gradient_color_7   = '#FF0000'   # red (highest)

4. Run the widget
5. Click on a different terminal
6. Done
