Environment:
Illustrator 30.3, Windows, ExtendScript / CEP.

When you look an item up by UUID, the wrapper returned by Document.getPageItemFromUuid() lies about its type for several subtypes. They all come back as "GroupItem":

// uuid belongs to a RasterItem (or PlacedItem / CompoundPathItem / SymbolItem / MeshItem):
var item = app.activeDocument.getPageItemFromUuid(uuid);
alert(item.typename); // -> "GroupItem" (expected the real subtype)

This makes type-based dispatch on UUID lookups unreliable. My current workarounds to recover the true type:

• Items with children: read item.pageItems[0].parent -> Returns correct object with the correct typename.
• Childless items (e.g. RasterItem): search the parent's typed sub-collections (rasterItems, placedItems, symbolItems, meshItems, …) by uuid.

Is there a better way to get the real typed object by UUID?
