Comment (by wildworks):

 I confirmed that the two scripts were swapped.

 {{{
 <html>
 <head>
 </head>
 <body>
 <script id="wp-importmap" type="importmap" crossorigin="anonymous">
 {
   "imports": {
     "@wordpress/route":           "http://localhost:8888/wp-
 content/plugins/gutenberg/build/modules/route/index.js?ver=48a77bfa70722b4254e4",
     "@wordpress/latex-to-mathml": "http://localhost:8888/wp-
 content/plugins/gutenberg/build/modules/latex-to-
 mathml/index.js?ver=e5fd3ae6d2c3b6e669da",
     "@wordpress/vips/worker":     "http://localhost:8888/wp-
 content/plugins/gutenberg/build/modules/vips/worker.min.js?ver=de1b94d254f242c2192e",
     "@wordpress/abilities":       "http://localhost:8888/wp-

   }
 }
 </script>
 <script type="module">
 /**

  */
 </script>
 </body>
 </html>
 }}}

 I have confirmed that this issue has been resolved.

 I confirmed that this issue still reproduces. However, it seems to occur
 in browsers other than Firefox as well. This might be a separate issue.
