bug: prevent ion-datetime selected value to be updated

[loopezz]

Bug Report

Ionic version:

[x] 4.x

Current behavior:
Updating the value while the picker is presented does also update the selected value within the picker.

Expected behavior:
The selected value should not be updated due to bad UX. It resets the user input.

• Do update current datetime which is visible in the UI list;
• Don't update current selected value while the picker is presented

Steps to reproduce:
Just select a custom time.

Thanks for the issue. This is resolved in the new datetime picker coming in Ionic 6.

Please see https://github.com/ionic-team/ionic-framework/blob/next/BETA.md for more on how to get started with the Ionic 6 pre-release. Thanks!
