were rendered in both katex-mathml and katex-html format.

There is the same error(show twice) when using or not using remark-mdx-math-enhanced.

import rehypeKatex from 'rehype-katex'
import remarkMath from 'remark-math'
import remarkMdxEnhanced from 'remark-mdx-math-enhanced'

const mdxOptions = {
  // See https://mdxjs.com/advanced/plugins
  remarkPlugins: [
    // E.g. `remark-frontmatter`
    remarkMath, [remarkMdxEnhanced, { component: 'Math' }]
  ],
  rehypePlugins: [
//    rehypeKatex
  ],
}
