IHM.json `Could not parse color from value '#00C00050'`

[lielvan]

Using Leaflet with maplibre-gl-leaflet, I tried to render
the VectorMap Style IHM.json.

I received the following console error:
Error: layers[207].paint.text-halo-color[8]: Could not parse color from value '#00C00050'

Seems to originate from this line:

VectorMap/Styles/IHM.json

Line 4026 in 9211701

"#00C00050",

Note:
The Style IHM+traces.json renders fine...
