According to the latest HTML spec, scrolling should be happening in the next task so there appears to be a bug here: a element: https://html.spec.whatwg.org/#the-a-element follow a hyperlink: https://html.spec.whatwg.org/#following-hyperlinks-2 navigate: https://html.spec.whatwg.org/#navigate navigate to a frament: https://html.spec.whatwg.org/#scroll-to-fragid 1261311 4 simon.fraser 2016-12-19 20:12:26 -0800 Scrolling is an async round-trip to the UI process, so that's not surprising. 1261316 5 rniwa 2016-12-19 20:38:34 -0800 (In reply to comment #4) > Scrolling is an async round-trip to the UI process, so that's not surprising. If we can’t fix it in WebKit, we should probably have the spec changed so that it’s fully async.
