checkPropsPostMutations renders each suggestion with mustache and writes the result into the DOM through dangerouslySetInnerHTML, but mustache only escapes interpolated values so its output is not a sanitization boundary, and the suggestion data can come from a remote src fetch. A response item like {"name": "
"} rendered through a {{{name}}} template runs its handler in the component shadow root. This routes the rendered markup through the AMP Purifier before insertion, the same way amp-mustache and amp-autocomplete sanitize template output.
