Взгляните на этот пример, он основан на вашем коде, я просто удаляю много вещей и оставляю важные, чтобы увидеть, как работает сортировка по областям. Как я уже говорил, слой плюс средство визуализации не помогли вам понять это. Просто щелкните, и вы увидите, что каждая функция была выбрана.

ОБНОВЛЕНИЕ:
После просмотра вашего обновления, я думаю, что лучше понимаю проблему, и я заметил кое-что, что я пропустил раньше, featureNavigation: false. Я почти уверен, что при нажатии выбираются все функции, проблема в том, что тот, который вам нужен, не появляется первым. Другими словами, у вас есть проблема с порядком, в котором всплывающее окно показывает выбранные функции.
Итак, я предложу вам простое решение, вручную откройте всплывающее окно с функцией желаний (в вашем случае то, что меньше площади). Для этого вам необходимо:
- отключить автоматическое открытие всплывающих окон
- обработать событие щелчка при просмотре
- использовать метод проверки результатов просмотра для получения функций
- открыть всплывающее окно с функцией desire
Взгляните на этот пример, который я сделал для вас, я добавляю дополнительное условие для извлечения некоторых функций, чтобы сделать его быстрее
