Whilst typing in the Data Value Input Fields in the Data Tab, pressing Enter or clicking away will completely clear the field.

Repro Steps:

1. Create a Studio Project with a MainPage.xaml
2. Navigate to the Data Tab and create a Data Structure and call it "TabViewModel"
3. Add 3 properties to this Data Structure: 1 string and 2 numbers.
4. Create a new Data Structure and name it "ScreenViewModel"
5. Add a property to this Data Structure and in its drop-down menu select "TabViewModel" and make it a collection.
6. Create a Data Set for ScreenViewModel and add an item in its Data Set values
7. Type anything into the item's Data Value Input Field, and press Enter.
8. Observe how the content in the field has been cleared.
9. Type something again into the item's Data Value Input Field, and click away to deselect the input field.
10. Observe how the DataField is cleared when the input field is deselected.

Expected result:
Hitting enter will finalize what was typed, not delete it entirely.
