Created attachment 477789 [details] Video demonstrating the issue It appears `window.scrollTo(0, 0)` does not work in iOS Safari when the current scroll position is within the bounds of a sticky element. Reduced test case: https://cdpn.io/pen/debug/QwNexwR?authentication_hash=jVMpoPjEWPok Code: https://codepen.io/OliverJAsh/pen/QwNexwR In the attached video I'm first clicking on the button to scroll the content a bit so it appears below the sticky nav (`window.scrollTo(0, 50)`), then clicking the button to scroll to the top (`window.scrollTo(0, 0)`). The `window.scrollTo(0, 0)` call has no affect in iOS Safari. It does appear to be working in macOS Safari, as well as other browsers like Chrome.
