// If you're setting `(x -> y)[0].style.opacity`
// There's 3 cases you need to handle:
// 1. The edge has no map.
// 2. The edge has a style map with opacity not existing
// 3. The edge has a style map with opacity existing
//
// How each case is handled:
// 1. Append that mapkey to edge.
// 2. Append opacity to the style map
// 3. Set opacity
//
// There's certainly cleaner code to achieve this, but currently, there's a lot of logic to correctly scope, merge, append.
// The tests should be comprehensive enough for a safe refactor someday
//

// reservedTargetKey = "opacity"
