transparent png background

[repriest]

2 questions:

1. Is it supposed to work with transparent PNG background? In my case it just substitutes transparent background with default white

2. background option does not seem to be working for me

Image itself

Gatsby image config:

{
  resolve: `gatsby-plugin-mdx`,
  options: {
    plugins: [
      `gatsby-remark-images`,
      `gatsby-remark-images-medium-zoom` // Important!
    ],
    gatsbyRemarkPlugins: [
      {
        resolve: `gatsby-remark-images`,
        options: {
          maxWidth: 590,
          linkImagesToOriginal: false, // Important!              
        }
      },
      {
        resolve: `gatsby-remark-images-medium-zoom`, // Important!
        options: {
          margin: 36,
          scrollOffset: 0,
          background: "#777"
        },
      }
    ],
  }
},
`gatsby-transformer-sharp`,
`gatsby-plugin-sharp`
