issue in parsing email reply for html content

below is code, I am extracting the mail body using mailparser which is text/html content
and trying to get latest reply using EmailReplyParser.parse_reply, but it is extracting complete message not the reply only

mail = mailparser.parse_from_bytes(file.read()
reply_text = EmailReplyParser.parse_reply(mail.text_html[0])

it is working file for text/plain content
mail = mailparser.parse_from_bytes(file.read()
reply_text = EmailReplyParser.parse_reply(mail.text_plIn[0])

any suggestions are appreciated, thanks in adavnce

Start at EmailReplyParser.parse_reply and compare the mail.text_html[0] path with the working mail.text_plIn[0] path. The issue provides no file or test location; done would mean parsing HTML returns only the latest reply rather than the complete message, with coverage for that input.
