I suspect that preload may be related.

The body contains this:

`<link rel="perload" href="/svc/shreddit/comments/r/firefox/t3_1mqmsv5?render-mode=partial&amp;seeker-session=true" as="fetch" />  <link rel="perload" href="/svc/shreddit/pdp-right-rail/related/firefox/t3_1mqmsv5?render-mode=partial&amp;seeker-session=true" as="fetch" />`

If I create an extension that does `str = str.replaceAll(/<link rel="preload" href="/g, "$&https://example.com/");`, then the content loads fine.

If I drop the preload tag, `str = str.replaceAll("preload", "perload");`, then some error in Reddit happens and the page does not load (but there is no red banner either).
