Hmm, when typing 2nd character which is same as autofilled first character, previously inserted text node for the first typing character is removed, then, another text node is inserted for new text. Then, it'll be replaced with another new node again. Finally, undoing does undo only the last inserted text node. Then, new padding `<br>` element is inserted with new transaction with clearing redo history.

Edit: The previous analysis is wrong.
This log is easier to understand than the previous one. According to this log, the last insertion occurred by autofilling. However, oddly, there is no placeholder transaction at this time. Why??
