I have a floating group “FloatingGroup Main back to top” that is not visible on page load, and is supposed to be visible when the scrolling position is not 0.
But I cannot see it appear on the page, and according to the debugger it is supposed to be visible.
Do you have any idea why a visible element is actually not visible ?
After looking at your page I think it has to do with where everything is placed. Your page height is ~41K pixels tall (not sure why it is so tall) and the element you named has a Y of the element is ~34K pixels. So this would put this element ~7000 pixels above the bottom of the screen and not visible to users. Try putting the floating element closer to the bottom of the page.
I think the problem may be in the alignment of your floating group. I assume you want it to float at the top right. But it is programed to be aligned to the botton left.
