Not sure why, but in our markdown files, HTML is still being considered as javascript and being formatted as if it was JSX. There are many weird situations where it is wrapping the text as if it is plain text that you would type in as content. There is an issue open on migrating eslint-plugin-html to the new processer API: BenoitZugmeyer/eslint-plugin-html#139. Also there is a comment related to this: BenoitZugmeyer/eslint-plugin-html#139 (comment). I guess we should disable eslint-plugin-html and leave embedded markdown formatting to prettier. For HTML, we can use @html-eslint though.
