good article, love it. one thing I don't like it, if I use a function that has "use cache" in the layout page, I need to wrap the layout page with suspense but on one upper level, why? page/component having the "use cache" function have to be wrapped with suspense boundary before it renders something like that and default loading page doesnt cover that for layout page. faced it in the current canary version,

can anyone please explain this line to me? Thanks in advance. I am confused that's why. Promise.all(promise).then(setSelectedDemo);
