描述

When pasting some text with at least two containers/paragraphs on two linebreaks, the text being pasted gets split, the first container (heading) gets on the correct location, and the remaining text gets pasted after the next paragraph.

Lexical version:

Steps To Reproduce

  1. Hit two Shift-Enter inside a paragraph on Lexical's editor
  2. Try pasting a text having two containers, a heading and a paragraph for example

Lexical playground exports: Playground 2023-07-24T13_10_22.747Z.lexical.zip

The current behavior

The first line of the text being pasted gets to the correct location, and the remaining text gets appended to the end of the paragraph.

The expected behavior

All the text gets inserted to the correct location, preferably keeping the same formatting from where it was copied.

研究方向
Investigate the clipboard plugin in `packages/lexical clipboard/`. Focus on the `$insertDataTransferForPlainText` or `$insertDataTransferForRichText` functions. Check how pasting into a paragraph with line breaks differs from normal paste. Use the provided playground export to reproduce the bug. Look for recent changes to clipboard handling that might have introduced the regression.
