package page doesn't load with javascript disabled

It doesn't work at all without javascript and before it was working

this pr likely caused the issue because earlier the package pages did not use any fallback, so when a package page was requested for the first time, the server would wait, render the full html, and send real content that worked even with js disabled, but this pr added spa fallbacks which means that on a cache miss the server now returns an empty html and expects the browsers js to load the data and render the page later, so when js is disabled the page has nothing to render and appears blank while already cached pages still work because they already have server rendered html saved.

could it be fixed?
