Inconsistent Details Panel Focus Behavior On Enter Pressed for Blueprint-Added Components

When editing a component property in the level viewport, if the component was added via the Blueprint Editor, pressing Enter after changing a value causes the details panel to lose focus. This interrupts the editing flow, requiring an extra mouse click to reselect the field. The behavior is inconsistent with components added via C++ or components added directly to instances in the level.

Expected Behavior:
The field remains focused and selected.

Actual Result:
Pressing Enter deselects the field, and focus is lost. The user must manually reselect the field with the mouse to continue editing.

1. Create a new Blueprint class (e.g., Actor).
2. In the Blueprint Editor, add a new component (e.g., Static Mesh Component).
3. Place an instance of the Blueprint in the level.
4. In the level viewport, select the instance and edit a numerical property of the component (e.g., scale).
5. Press Enter after typing a new value. This deselects the field, and focus is lost. The user must manually reselect the field with the mouse to continue editing.
