Describe the Bug

Astro icons works as expected on all pages, apart from Error pages (400, 500). On these pages I can see that the SVG element is added with the correct <use.../> tag, however the Symbol tag with the svg code inside is missing - as if the astro-icons has identified that it already exists somewhere on the page so can just reference it, but it obviously doesn't...

Interestingly it's working fine locally. And if I use is:inline directive it also works.

What's the expected result?

The first time an icon is used it should render the symbol tag with the svg code, then if it is used again it can be referenced and symbol isn't required.
