In Jenkins 2.347 (I did not check which release introduced this bug) the New Item dialog validation forces the selection of the Item Name (if empty) when I am trying to enter a value in the Copy From field.

Steps to reproduce:

1. Select New Item
2. Click and select the text field Copy From (without entering a value in Item Name)
3. Type a character
4. Jenkins Validation writes error message "This field cannot be empty, please enter a valid name" in Item Name field.
5. Jenkins moves focus from Copy From to Item Name

Expected behavior

• Jenkins should never change the focus while I am typing in a field just to present a validation message in another field. A validation message should only be visible if the user leaves a field (or presses ok)
