External Images Arent Responsive In Gatsby With Gatsby Remark Images

Using `gatsby-remark-images` images called from another site weren't responsive for me with:

Code

resolve: `gatsby-plugin-mdx`,
options: {
    extensions: ['.mdx', '.md'],
    // a workaround to solve mdx-remark plugin compat issue
    // https://github.com/gatsbyjs/gatsby/issues/15486
    plugins: [
        `gatsby-remark-images`,
    ],
    gatsbyRemarkPlugins: [

        {
            resolve: `gatsby-remark-images`,
            options: {
                linkImagesToOriginal: false,
                maxWidth: 800,
                quality: 82,
                loading: "eager",
                disableBgImage: true,
            },
        },

        ... etc...
