2. Create UI Document (Create > UI Toolkit > UI Document)
3. Double-click on the newly created UI Document to open UI Builder
4. Drag Label to the Hierarchy
5. Select newly created Label and click on kebab menu next to Text property in the Inspector
6. Select “Add binding…” to open Add Binding window
7. Select any of the Scriptable Objects and press “Add Binding” button
8. Press on the Binding icon and select “Unset” option

Actual results: Text input field is distorted and property name is greyed out

Reproducible with versions: 6000.0.53f1, 6000.1.11f1, 6000.2.0b9, 6000.3.0a1
