TilesFadePlugin: TypeError when engineData.scene is null in resetVirtualChildren

[aidannewsome]

Bug

TilesFadePlugin throws a TypeError: Cannot read properties of null (reading 'clone') during resetVirtualChildren. It appears the plugin iterates over tiles and calls engineData.scene.clone() without checking if scene is null first.

This seems to happen when a tile is disposed before its fade transition completes.
