This is due to the `image_src` field not being included in the `$url_options` whitelist (which only contains `url`, `button_link`, `button_url`), so it never receives `esc_url_raw()` at save time. On the server side, the value is rendered into a `data-image` HTML attribute using `esc_attr()`, which encodes double quotes as `&quot;`. However, the client-side JavaScript carousel code in `custom.unified.js` reads this attribute using jQuery's `.data('image')`, which returns the browser-decoded value (with `&quot;` decoded back to `\"`). The decoded value is then concatenated directly into an HTML string and injected into the DOM via `jQuery.after()` without re-escaping.
