Gecko and Presto get this right: the scrollbar appears once there is overflow. 555864 1 simon.fraser 2012-02-13 19:04:51 -0800 This is somewhat by design. We don't want to slow down accelerated transform animations by having to recompute overflow for every frame. Perhaps we could recompute overflow at the start of the transition, using the final transform value though. 555867 2 bzbarsky 2012-02-13 19:08:49 -0800 If you think the spec should allow this behavior, then it should probably do so explicitly... 1971656 3 ahmad.saleem792 2023-08-16 15:25:35 -0700 WebKit ToT (266957@main) only get 'horizontal' scrollbar once the 'text' go out of window view while Firefox Nightly 118 and Chrome Canary 118 show 'horizontal' scrollbar from start.
