Bug Report

Summary

HTTP/Response::getHeaders() returns header like key:<space>value even when the header sent by application is key:value .

Current behavior

sendResponse(method, requestTarget, resOrStream, 200, JSON.stringify(incomingHeaders2, null, 2), {
 'Content-Type': 'application/json',
 'X-Response-Header-Downstream-To-App': 'Value 3',
 });
}

However when reading headers from laminas/API/response::getHeaders() , I received the headers like:

'Content-Type': 'application/json',
'X-Response-Header-To-App': 'Value 3'

How to reproduce

Any node js application which sends header in above format and laminas application received the requests and print headers.

Expected behavior

headers should propagated as it is what framework received.
