// Submit Logic:
// * ✅ Value:
//    * merged value using controlled value, if not, use stateValue
//    * When merged value change, [1] resync calendar value and submit value
// * ✅ Calender Value:
//    * 💻 When user typing is validate, change the calendar value
//    * 🌅 When user click on the panel, change the calendar value
// * Submit Value:
//    * 💻 When user blur the input, flush calendar value to submit value
//    * 🌅 When user click on the panel is no needConfirm, flush calendar value to submit value
//    * 🌅 When user click on the panel is needConfirm and click OK, flush calendar value to submit value
// * Blur logic & close logic:
//    * ✅ For value, always try flush submit
//    * ✅ If `needConfirm`, reset as [1]
//    * Else (`!needConfirm`)
//      * If has another index field, active another index
// * ✅ Flush submit:
//    * If all the start & end field is confirmed or all blur or panel closed
//    * Update `needSubmit` mark to true
//    * trigger onChange by `needSubmit` and update stateValue
