engine.fasthttp#FormParams function can not receive HTML array parameters

I post thr form like:

<form action="/handler" method="post">
    <input name="test[]" value="test1">
    <input name="test[]" value="test2">
    <button type="submit">submit</button>
</form>

but only get one value

e.Post("/form", func(c echo.Context) error {
        return c.String(http.StatusOK, fmt.Sprintf("%v", c.FormParams()))
    })

engine.fasthttp output:

map[test[]:[test2]]

engine.standard output:

map[test[]:[test1 test2]]

Can you try to run it with plain fasthttp server?

// FormParams implements `engine.Request#FormParams` function.
func (r *Request) FormParams() (params map[string][]string) {
    params = make(map[string][]string)
    mf, err := r.RequestCtx.MultipartForm()

    if err == fasthttp.ErrNoMultipartForm {
        r.PostArgs().VisitAll(func(k, v []byte) {
            // TODO: Filling with only first value
            // params[string(k)] = []string{string(v)}

            if _, has := params[string(k)]; has {
                params[string(k)] = append(params[string(k)], string(v))

            } else {
                params[string(k)] = []string{string(v)}
            }
        })
    } else if err == nil {
        for k, v := range mf.Value {
            if len(v) > 0 {
                params[k] = v
            }
        }
    }

    return
}

i modify the code like this and it works well
