Summary: Repeater+Flow has no reliable way to transactionize/batch insertion, e.g. `Flow.positionCompleted` is useless in a function that can change the Flow's size, and transition events like populated and similar aren't available. Refactoring this to be a ListView isn't appealing because it would mean the code loses the property of being reused for both the bar and the popup, and therefore is well-tested already. This brings down the number of `updateSize` calls when opening the dialog for a group of five from five to one.
