compute-scroll-into-view: Scrollable container not detected

Not sure which repo you prefer issues on, but I have an issue where I have a horizontal container that’s not detected as “scrollable”. If I log out all the actions computed by compute-scroll-into-view, the container isn’t listed. This happens even though the scrollWidth is definitely wider than clientWidth. (I logged to verify.) Is there a way to force computation that a container definitely is scrollable and to set the scroll position?
