Datebox / Timebox need two clicks on set button when editing input

[zoulou2356]

Steps to reproduce:

1. Open a datebox / timebox
2. Click in a input and edit a value with the keyboard
3. Click on the Set button

Actual result:

• The focus is lost by the input and the "postrefresh" method occurs (a second click on the Set button is needed to close the datebox / timebox)

Expected result:

• Only one click on the Set button should be needed to close the datebox / timebox when editing an input with the keyboard

This will hit with 4.1.0, likely later today. Certainly in the next week.
