There's some ugly active tab index management going on! Very much need to revisit this / open to suggestions.

In many instances, I want the active tab index to be the last in the list. Otherwise there can be some strange behavior, for example on staging:

Yeah this is an issue in the List component which is avoided by only allowing a single active item at a time (it's not possible to add when there's an active item). That solution won't work here due to the map driven nature of the component.

It's going to be a little tricky as setFeatures() is async, but we can take the length from geojson["EPSG:3857"].features reliably I believe.

Something like this might work?

const newFeatures = geojson["EPSG:3857"].features;
setFeatures(newFeatures);
setActiveIndex(newFeatures.length - 1)

I've not tried this so I might be off the mark a little here and treading over old ground you've already worked through.

An alternative might a useEffect() to catch changes to features.length and tie the update to setActiveIndex to that?
