Description: In version 1.9.0, when opening DatePicker with text input mode and a default selection, the cursor was positioned at the end:

Since version 1.10.0 it is positioned at the beginning;

Expected behavior: For usability, it is preferable to position cursor at the end, since in order to delete the default selection, user must now change cursor position first.

Minimal sample app repro: The issue can be reproduced with the Catalog app -> Date Picker. Set Default Selection to Today, and Input Mode to Text Input.

The problem seems to have been introduced with commit 4032a741127b4715c3bbcd4cab08494b39ae5bdb

Android API version: API 32
