Same SVG. Shows up on one page, 404s on another

I have some SVGs that are charts to illustrate an article.

When they are placed in the article in question, they fail to render.

But when I place them in a separate post, they appear as expected:

It doesn’t seem to matter which sort of image block I use to place them. Or which particular image gets placed.

I have tried disabling WP’s Lazy Loading using a Code Snippet and the only thing that does is hide the browser’s broken image src icon.

How can I get these images to render?
