IDE loses defaultValue on dependent field update

Setup:
2 DropDown lists, where the second DropDown's value depend on the value of the first DropDown.

Steps:
1. Select a value from DropDown 1
2. DropDown 2 now has the defaultValue selected
3. Select a new value from DropDown 1

Step 4 - Expected:
DropDown 2 should now have the new defaultValue selected

Step 4 - Behavior:
DropDown 2's valueChoices are updated, but no defaultSelection is done
