这个 bug 的原因是，富文本（cell.p）被当做格式被粘贴了，它不仅含有富文本的格式，也含有富文本的文本，这会与单元格文本（即 cell.v） 冲突。为剥离影响，预期暂调整为：「选择性粘贴-仅粘贴格式」将不会粘贴源富文本格式（cell.p），只粘贴源单元格格式（cell.s），粘贴后，目标单元格的原本富文本格式可能会受影响，但这是预期中的 @zhaolixin7

The reason for this bug is that the rich text (cell.p) is pasted as format. It not only contains the format of the rich text, but also contains the text of the rich text, which will conflict with the cell text (i.e. cell.v). In order to peel off the impact, it is expected that the temporary adjustment is: "Paste Special - Paste Format Only" will not paste the source rich text format (cell.p), but only the source cell format (cell.s). After pasting, the target cell The original rich text format may be affected, but this is expected @zhaolixin7

粘贴为公式时，不含公式的文本也会被粘贴下来
