# Open the “My project(13).zip“ project
# Open the “SampleScene“
# Open the “MyDocument” uxml file in the Project window using UI Builder
# Select “Label” in the Hierarchy tab of the UI Builder window (“MyDocument.uxml“ > VisualElement > Label)
# Click the pink icon (or three dots) next to "Text" attribute in the “Attributes“ tab of the UI Builder
# Select “Edit binding…“
# With the “Edit Binding” window open, Reimport the “MyDataSource.cs” script in the Project window
# Observe the “Edit Binding“ window

Expected results: The “Edit Binding“ window closes
