Better inline preview for postfix completion Better inline preview for postfix completion, a proper implementation of c5686c89413b3c6eead7b39637381ee353f8c05c. Here editors may filter completion item with the text within `delete_range`, so we need to include the `receiver text` in the `lookup` (aka `FilterText` in LSP spec) for editors to find the completion item.
