3. Press "Add Node"
4. Drag the Node around

Actual result: Assertion error thrown in the Console

Reproducible with: 1.0.0-preview.15, 1.0.0-preview.18 (2020.3.23f1)

  1. Resolution Note:

    This issue only occurs with the preview UI package installed in 2020 LTS.
    We are no longer maintaining this package and are focusing our priorities on supporting 2021 LTS where UI Toolkit is officially supported at runtime.
