A yellow triangle appears when image file from Assets/Editor Default Resources dragged into UI Builder



Reproduction steps:
1. Open the "" project
2. Open Assets > EditorGuiUtilityLoadEquivalent.uxml
3. In the UI Builder's Hierarchy select VisualElement
4. Drag the image from Assets > Editor Default Resources

Expected result: The dragged image is shown in the UI Builder Viewport
Actual result: Yellow triangle is shown

Reproduced with: 1.0.0-preview.18 (2019.4.37f1, 2020.3.31f1), 1.0.0 (2021.2.17f1, 2022.1.0b13, 2022.2.0a8)

  1. Resolution Note:

    We cannot use editor resources in UI Builder (UI assets have no way to reference editor resources). Please use assets found in the current project.

  2. Resolution Note (2022.1.X):

    Port canceled as we transition to 2022.2 (2022.2.X port is active or already resolved)

  3. Resolution Note (2021.2.X):

    No planned fixes for this version (LTS support is still active)

  4. Resolution Note (2020.3.X):

    Not going to be fixed as this can only be fixed in packages (UI Builder and/or UI Toolkit) which are not actively maintained for 2020.X editors. Please consider using the Unity 2021LTS or more recent editions.

  5. Resolution Note (2019.4.X):

    2019.X ports cancelled (not supported by UI Builder and/or UI Toolkit packages)
