Escaping out of a command text field in an NPC clears the inputted text

When escaping out of the command text field inside the "advanced settings" interface for NPCs the text inputted text is cleared. This occurs if not in full-screen view of the command text field. This issue does not affect the name text field for buttons or the command text field once in full-screen view. The only current workaround for this issue is to input the text and then press the Xbox button to open up the Xbox menu (this closes the Xbox keyboard interface and saves the inputted text). Alternatively, opening the command text field in full-screen view is an acceptable solution.

Steps to Reproduce

1. Summon an NPC

2. Open the NPC interface

3. Select "advanced settings"

4. Select "add command"

5. Input any text and press "back" to escape the text field.

Expected Outcome
The text field should be exited and the inputted text should remain.

Actual Outcome
The text field is exited but the inputted text is erased
