Unexpected handling of long options

Where do the long options go? they don't tigger error or don't appear to be passed to scripts

```json
  "scripts": {
    "dummy": "echo dummy",

```

```sh
❯ run-s --mode=prod --kalasmajas=3 dummy

> dummy
> echo dummy

dummy
```

for comparision, unknown short option does trigger an error:

```
❯ run-s --mode=prod --kalasmajas=3 -v dummy
ERROR: Invalid Option: -v
```
