[ Svelte 5 + SortableJS ] Cannot read properties of null (reading 'nextSibling') since 5.0.0-next.162

[anthonyivol]

Describe the bug

I get this error when reordering a keyed each block with SortableJS since 5.0.0-next.162 : Cannot read properties of null (reading 'nextSibling') : repl
No error with manual reordering : repl
No error without the each key : repl
