Canvas max height?

I am trying to make a website with xojo web, but I find that there is a limitation of canvas max height, when I setup the height to 3000, I can not see the whole canvas on xojo ide, please does anyone know how I can make a long web site?

I find the trick, when you resize the hight to 2000, 3000, you will only see the middle of the page, you won’t see the top and button part, but then you resize your main xojo window, then you can see the whole canvas again, how strange.

Just scroll down with the mouse wheel or by swiping the Magic Mouse on Mac.
