## Repro steps - Open https://demo-webkit-scroll-lock.glitch.me in Safari Browser ### Case a - a.1 Make sure Safari Address Bar is **visible** - a.2 Click lock scrolling button, this will add `overflow: hidden` to the body element - a.3 Try to scroll up and down ### Case b - a.1 Make sure Safari Address Bar is **HIDDEN** - a.2 Click lock scrolling button, this will add `overflow: hidden` to the body element - a.3 Try to scroll up and down ## Expected - Case a: locks scrolling / document does not scroll - Case b: locks scrolling / document does not scroll ## Actual - Case a: successful, locks scrolling / document does not scroll - Case b: fails ## Conclusion The visibility of the address bar seems to interfere with scrolling and Safari's ability to apply consistent overflow rules on the scrolling element when it's both hidden and visible.
