Importing modules using import maps in the client

[dkolba]

Is it supported to use <script type="importmap"> within a component during development?

I always get An import map is added after module script load was triggered. in the browser console while running in dev mode. Import maps seem to expect to be loaded before everything else on the page and fresh_dev_client.js is always the very first script being loaded.

        <script
          type="importmap"
          dangerouslySetInnerHTML={{
            __html: '{ "imports": { "a": "/a.js"} }',
          }}
        />
        <script
          type="module"
          dangerouslySetInnerHTML={{
            __html: `
              import { a } from "a";
            `,
          }}
        />
