Still doesn't look like it, this is the kind of interactivity I expect.

Where editing the code, immediately shows the GUI related changes on the neighbouring frame.

While what I see on https://leptos.dev/ is just screenshots, and there is nothing on that documentation you linked that provides the same interactive experience, one has to explicitly start a developer sandbox to host the whole machinery, and even requires a codebox account for editing.
