Cms: Invoking exit efter a setting content-type header reverts to text/html

[jishi]

Description

When I run a template with

{% if craft.app.request.headers.get('x-request-type') == 'fetch' %}
  {% header 'Content-Type: text/plain; charset=UTF-8' %}
  {{ include('types/_' ~ entry.type) }}
  {% exit %}
{% endif %}

because I just want to render a partial (without the extra markup required for a full page), the exit call makes it ignore my explicit content-type header.

This can of course be circumvented with an else, but it doesn't seem like this was intentional, and sounds like a bug. Also cleaner to fast exit IMHO.

Steps to reproduce

1. Set content-type with a header call.
2. Add an exit somewhere after all content.
