The tooltip of the install-per-version chart stops working when switching chart

On the initial page load, the new install-per-version chart has a tooltip on hover giving the value. But as soon as you switch to a different chart, the tooltip stops working (even when going back to the initial chart).

Reproduce the issue by hovering the install-per-version chart, switching to another chart, and returning to the original. Trace how chart switching affects tooltip behavior; done means the tooltip displays values on hover for every chart after switching between them.
