I have a chart that can display up to three different series (one line and two different columns). The two column series are set with their `isVisible: false` by default, so that the user has to tap the legend item to "enable" them and display them in the chart.
If the chart begins with one of the optional series as not-visible and then re-builds due to a state change, that series' legend item will flash the enabled color before animating back to the disabled color. If another state change causes a third build, what often happens is that disabled series suddenly becomes fully enabled and displays in the chart.
I would expect the `isVisible: false` to be respected regardless of any rebuilds unless the user has manually enabled it by tapping the legend item.
