RSS-plugin causes --pathprefix to be output twice in the regular site

[lsolesen]

When enabling the RSS-plugin like this:

  // RSS-feed
  eleventyConfig.addPlugin(feedPlugin, {
    type: "rss", // 'atom' or "rss", "json"
		outputPath: "/feed.xml",
		collection: {
			name: "posts", // iterate over `collections.posts`
			limit: 0,     // 0 means no limit
		},
		metadata: {
			language: "en",
			title: "Blog Title",
			subtitle: "This is a longer description about your blog.",
			base: "https://example.com/",
			author: {
				name: "Your Name",
				email: "", // Optional
			}
		},
    htmlBasePluginOptions: {
      baseHref: '/local-test/',
    }
  });

Having:

import { EleventyHtmlBasePlugin } from "@11ty/eleventy";

export default async function (eleventyConfig) {

  // Make it possible to have the site served in a sub directory
  eleventyConfig.addPlugin(EleventyHtmlBasePlugin);
};

And I run my site with:

``´
"watch:eleventy": "eleventy --serve --pathprefix=/minimal-mistakes/",

I get the following output in my regular site:

``` Removing this part from the setup of the RSS-plugin just gives me:

    htmlBasePluginOptions: {
      baseHref: '/local-test/',
    }

<link href="/minimal-mistakes/minimal-mistakes/minimal-mistakes/feed.xml" type="application/atom+xml" rel="alternate" title="Minimal Mistakes Feed">

Removing the EleventyHtmlBasePlugin from my config, gives me:

So the pathprefix is outputted twice for my pages without me enabling the module at all.

This issue has also been created in the main 11ty repos - 11ty/eleventy#3547
