Why isn't there a way to add a caption to a local image in one of my Obsidian markdown notes?

Here is another possible workaround I’m currently using. You can display the image’s alt text as figure caption using the following CSS snippet:

.image-embed[alt]:after {
    content: attr(alt);
    display: block;
    margin: 0.2rem 1rem 1rem 1rem;
    font-size: 90%;
    line-height: 1.4;
    color: var(--text-faint);
}

Here an example:

Please note, however, that inline Markdown syntax in the alt text will be not interpreted.
