This problem occurs on the mobile version of the creator hub, in any charts.
The tooltip does not hide when the chart that displays it is above (or below) the edges of the screen, because of this, the tooltip remains on the screen and covers a small part of the site. It hides only if you click on any part of the site (except the charts themselves)
Ideally, this tooltip should be hidden as soon as the chart is beyond the edge of the screen or the page starts scrolling.
This problem is difficult to explain, but there is a video demonstration where this problem is visible
This problem is not serious, but quite annoying.
