Response setHeaders overwrites setContentType

[linxlad]

Reponse setHeaders is scrubbing setContentType.

Expected and Actual Behavior

Expected:
I expected the reponse->setHeaders to merge with what was already in headers.

Actual :
I had response->setContentType('application/json') before response->setHeaders. The result meant I was losing the desired content type and it was reverting back to text/html.

Working:

$this->response->setHeaders($headers);
$this->response->setContentType('application/json', 'UTF-8');

Not working:

$this->response->setContentType('application/json', 'UTF-8');
$this->response->setHeaders($headers);

@linxlad

Well not sure what you exactly do further but $this->response->setContentType('application/json', 'UTF-8'); is most likely not needed just do:

$model = $model->toArray();
return $this->request->setJsonContent($model);
