Description

Duplicating a sprite was reported to drop or lose code. All reports pre-date the April 2026 hotfixes, and this is believed resolved by the shadow-ID fix deployed 2026-04-29 (scratchfoundation/scratch-blocks#3570, scratchfoundation/scratch-editor#543) or an earlier hotfix. Filing this so the fix can be confirmed on the live site and closed, rather than assumed.

If you can still reproduce code loss when duplicating a sprite on the current scratch.mit.edu, please comment with steps.

Part of scratchfoundation/scratch-editor#533.

Research direction

Start on the current scratch.mit.edu site and reproduce the reported sprite-duplication workflow, checking whether the duplicated sprite retains its code. Compare the result with the shadow-ID fixes in scratchfoundation/scratch-blocks#3570 and scratchfoundation/scratch-editor#543; done means confirming the issue is resolved or commenting with reproducible steps if code loss remains.
