Check the menu on top right
If you click on any of the buttons on that menu, you can now go to that page using wixlocation.to. But once on any of those subpages, clicking the menu does not show it again which makes little sense.
I get no errors on editor preview console or the code editor itself either.
I am experiencing the same issue when I try to have the menu pop down with mouse-in trigger as well, but once you move 1 page anywhere on this menu, all that stops working.
