For some reason, when I click reply button Thunderbird and an unwrapped previous message will be quoted in the reply, the wrapping preferences don't affect it and the quote will be written as in the message source. Reproducible: Always Steps to Reproduce: 1. Reply to any unwrapped plain text message Actual Results: The message quote will not be wrapped as it should regarding the composing preferences. Expected Results: Reply should be wrapped in the defined width and quote marks (>) added in front of each line.
If the original message is text/plain without format=flowed, then yes, we do not automatically wrap the quoted text. This is deliberate; see the duplicate. We also do not wrap quoted HTML text that appears within a <pre> block, for the same reason. *** This bug has been marked as a duplicate of 196033 ***
