- Implement proper button hiding/showing workflow for datepicker inputs
- Buttons now hidden initially when datepicker opens
- Buttons appear only after date selection, not immediately
- Datepicker closes automatically after date selection
- Enhanced CSS specificity for reliable button control
- Robust fallback methods for datepicker closing
- Update to version 25.0.5
