Plone 6.0.4 Endpoint @querystring-search GET vs POST - GET Method didn't return Metadata Fields

Plone Support Add-on Development

In Plone 6.0.4 a GET Request to REST-API Endpoint @querystring-search is possible. I see two diffrent Results if i change from POST to GET Method. My Question: Why? It's a Bug or a Feature?
The requested metadata_fields are ignored in the GET Request, but in the POST Request all is fine.

Endpoint @querystring-search with POST Method

const url = "http://myplone.local/@querystring-search"
const data = {
    "query": [{
        "i": "portal_type",
        "o": "plone.app.querystring.operation.selection.is",
        "v": ["News Item"]
        }],
    "metadata_fields": ["effective", "CreatorFullname", "targetgroup", "getIcon", "image_scales"],
    "sort_on": "effective",
    "sort_order": "descending",
    "fullobjects": false,
    "limit": 30,
    "b_start": 0,
    "b_size": 30
};

const options = {
    headers: {
        "Content-Type": "application/json", Accept: "application/json",
    },
    credentials: "same-origin",
    method : "POST",
    body : JSON.stringify(data)
};

fetch(url, options)

This is one result item in the response of the POST request:

It is probably better to open an issue either on GitHub - plone/plone.restapi: RESTful API for Plone. or GitHub - plone/Products.CMFPlone: The core of the Plone content management system
