### Summary The horizontal scrollbar is hidden from the user at the bottom of the page, on long pipelines. This makes it very frustrating to scroll from left to right. One has to first 'scroll all the way down, then back up again. And if the desired view is not realized, this has to be repeated. While true, on a touchpad or a mouse with horizontal scroll, this can be avoided, but horizontal scrollwheels are not the norm. I guess nobody is ~Dogfooding this :) I blame Macbooks :parking: #### Relevant user research findings Identified in https://gitlab.com/gitlab-org/ux-research/-/issues/2429+ > The horizontal scrolling of the pipeline graph display is really confusing because the horizontal scrollbar is often hidden off the bottom of my browser. ### Steps to reproduce Create a pipeline with many jobs, of which some parallel ### Example Project https://gitlab.com/gitlab-org/gitlab/-/pipelines/184481762  ### What is the current *bug* behavior? No scrollbar until you scroll down to the very bottom ### What is the expected *correct* behavior? The scrollbar is locked to the viewport or moved to the top of the div ### Possible fixes While https://stackoverflow.com/questions/25200424/horizontal-scrollbar-only-appearing-at-bottom-of-page#25200557 speaks of a bug to be solved, the approach might be similar?
