GetBaseColor does not return expected color

[RxxChance]

It seems that the following code in the WASM wrapper may cause GetBaseColor to ignore theme colors:

Original Code:
cmd/main.go

if len(args) == 3 {
	themeColor := args[2].Int()
	ret["color"] = f.GetBaseColor(args[0].String(), args[1].Int(), &themeColor)
}
ret["color"] = f.GetBaseColor(args[0].String(), args[1].Int(), nil)
return js.ValueOf(ret)

Even when len(args) == 3, the ret["color"] set with the theme color is immediately overwritten by the next line with nil as the theme.
As a result, GetBaseColor always ignores the theme color.

I’m not familiar with Go, so I might be mistaken.
