Xcode scene editor not displaying svg textures from reference nodes

While working with SVG textures, it seems that the Xcode Scene Editor is not displaying the texture in an SKReferenceNode. Instead, it just shows an X placeholder.

To replicate this, simply:

• Create a new Game template project in Xcode
• Add a new scene .sks file that contains a SKSpriteNode with an .svg texture
• Drag the newly added .sks file into the main game scene and you'll see the X placeholder image instead of the proper texture

Has anyone dealt with this problem? Is there any known workaround to make Xcode display the textures properly? This is using Xcode Version 13.1 (13A1030d) on macOS Big Sur 11.6.1.
