I meet an unfold-able headline now. Then I record a video to show this
unfold-able headline. I executed command "describe-text-properties".
Afterwards, I closed the buffer, then re-open the file to show the
headline can be expanded normally, and show the subtree content.

Here is the uploaded video (P.S, I know video link is not a good way to
archive information in mailing list, but this problem seems can't be
text-described simply. Sorry about this.):
