Svelte Tutorial Universal State updating without $state

In universal section, it says "But it’s a normal object, and as such nothing happens when you click the buttons.".
However, the buttons does, in fact, change when I click on them…

Jajajaja I was about to just literally post the same issue!

Here some proof:

The component is in legacy mode, so it works because it operates like in svelte 3/4.
If you enable runes by adding <svelte:options runes={true} /> to the component, it does require the suggested solution.

Very confusing, had the same issues in some REPLs too, because it defaults to legacy mode when no svelte 5 features are detected or not explicitly set to runes mode.

@hanszoons Your reply could be a side note in the tutorial.

Perhaps runes mode should be set by default on the tutorial? At least to not confuse beginners.

The playground has a indicator telling you if it's in runes mode.
