When horizontal scrolling on a graph drawn with https://en.wikipedia.org/wiki/Module:Graph on the mobile version of a page, e.g. at https://en.m.wikipedia.org/wiki/Demographics_of_Japan, the loading spinner appears from behind the graph and obstructs the view of it. Possibly related to: T275932: As loading spinner is always visible, border flashes when graph height is narrow (less than 47px).
