Created attachment 474464 [details] The VO focus ring stays on the top of the page and does not follow the currently being focused element What's not working: According to MDN (https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/drawFocusIfNeeded), the drawFocusIfNeeded API is supported on Safari. However, when using VoiceOver with Safari 18.3, the focus ring of the VoiceOver cannot position correctly on the currently being focused element, see the attached gif, the VoiceOver focus ring just stays on the top of the page. Here is the demo app I am using for testing: https://jsbin.com/zofuzah/edit?output Also I tested on iPhone 15 with Safari 18, the VoiceOver cannot focus on the element that is being focused. What's working: Tested on Chrome v133.0.6943.142, the VoiceOver can focus on the element properly. Environment: - Machine: Apple M1 Pro - Mac OS: 15.3.1 (24D70) - Safari Version 18.3 (20620.2.4.11.5)
