Weird issue. Looks like chrome needs the full URL. The following seems to work because it changes the URL from poster="/image.webp" to poster="http://localhost:3000/image.webp"

import { onMount } from "solid-js";

// ...

<video
        ref={(node) =>
          onMount(() => {
            node.poster = node.poster;
          })
        }
        poster="/image.webp"
        src="/some_video.mp4"
      ></video>

If I use it like follows it also works
<video poster="http://localhost:3000/image.webp" src="/some_video.mp4"></video>
maybe worth adding an issue into chrome bug list https://issues.chromium.org/issues
