**Issue Description:** I found an issue while working with `ion-datetime-button`. **Steps to Reproduce:** 1. Open the `ion-datetime-button`. 2. Navigate to the next month. 3. Close the date picker without selecting a date. 4. Open the date picker again and select any date. **Actual Behavior:** After selecting a date, the calendar continuously switches between months automatically. Additionally, when trying to manually navigate back to the previous month, the component does not allow it. **Additional Notes:** This issue appears to occur specifically after navigating to another month and closing the picker before making a selection. ### Expected Behavior **Expected Behavior:** The calendar should remain stable after reopening and selecting a date, and manual month navigation should work normally. ### Steps to Reproduce **Steps to Reproduce:** 1. Open the `ion-datetime-button`. 2. Navigate to the next month. 3. Close the date picker without selecting a date. 4. Open the date picker again and select any date. ### Screenshots <img width="715" height="593" alt="Image" src="https://github.com/user-attachments/assets/20de3085-6eab-43a6-8350-c47ad03452cd" /> <img width="732" height="583" alt="Image" src="https://github.com/user-attachments/assets/0f30f750-aa29-451c-a995-d61b195ccd70" /> <img width="687" height="584" alt="Image" src="https://github.com/user-attachments/assets/23d06d30-b8f9-4a11-9e87-d216c365a818" /> <img width="697" height="585" alt="Image" src="https://github.com/user-attachments/assets/065d61ae-068e-4517-bd57-3bd4b0bc038f" /> ### Operating System Windows and Macbook ### Browser Chrome ### Version _No response_ ### Additional Information This issue is arising only in Ionic 8
