Custom API endpoint always inserts HTML tags regardless of what I set $response.setContentType() to

I’m trying to create a custom API endpoint that responds with plain text. No matter what I do, the response always gets returned as HTML. As an experiment, I also tried a JSON response, and it had the same issue.

Here’s a simplified example to demonstrate the problem. I create a terminal page at /xwiki/bin/view/api/test with the following content:

{{velocity}}
#if ($stringtool.contains("$!request.getRequestURL()", "/get/"))
  #set ($discard = $response.setContentType('text/plain'))
  #set ($name = "$!request.name")
  Hello, $name
#end
{{/velocity}}

If I call this endpoint with:
https://www.example.com/xwiki/bin/get/api/test?name=Rob
the response looks like this:

<p>Hello, Rob</p>

For more complex responses with multiple lines, I get a <br> inserted between each line.
I get the same output whether I go through the browser (Chrome/Brave) or via the command line using curl.

What do I need to do to force a plain text response of:

Hello, Rob

If it matters, I’m running XWiki behind an Apache reverse proxy with the following settings:

ProxyRequests Off
  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>
  ProxyPreserveHost On
  ProxyPass /xwiki http://localhost:8080/xwiki nocanon
  ProxyPassReverse /xwiki http://localhost:8080/xwiki
