Visit our PWA at: https://editor.construct.net Dismiss any startup prompts until you see the start page. Try and scroll the start page. If it does not scroll, resize the browser window. As you resize the window the page alternates between the correct layout (scrollable with some extra content at the bottom), and incorrect layout (a scrollable div overflows all the way off the bottom and the page is not scrollable). This reproduces in both Safari 13.1 and TP 112, and works correctly in Chrome and Firefox.
Possibly a grid layout issue. <ui-body> does not become scrollable.
