redo and undo are wrong for insert operation records

[zhugexiaogou666]

Description
redo and undo are wrong for insert operation records. When Replace is selected, undo will also record the last insertion operation before insert, causing the last operation to be lost during undo.

Recording

In this case, I think "insert_text" 5, should not appear in the undo stack

In this case, I think the input box should not be cleared

Expectation
I hope that when I perform the insert operation, what undo records is the data when I selected the operation in the last step.
