Check that Backspace, Delete, Return, typing, paste, cut and bold keep the text outside their range in order over every caret and range of every small document, with a link, a read-only inline, a required title and a one-text code block among them, that the result stays canonical and that one undo gives back the document. Use before and after changing packages/plitejs/src/transforms-text/delete-text.ts, merge-nodes.ts, slice landing or another file in its coverage record, when the delete-paste-ranges step of pnpm check fails, or when fixing a delete, join or paste bug a tester found.
