When using the Google Maps Address field, users are unable to change addresses. This is also exists on the registration form of the EasyProfile Demo. To replicate:

Enter an address in the address field.
Select the address.
Erase the address.
Enter a new address in the address field.
Select the new address.
** The address field reverts back to the first address entered while the map moves to the new address.
** If you use the keyboard arrows and enter key to select the new address, it works as expected. However, when using the mouse to select the address always reverts back to the first address entered.
