As a test, please install the beta for Thunderbird 36 from https://www.mozilla.org/en-US/thunderbird/channel/ this if the feature complete upgrade that will be released in the current month (I hope). There have been some fixes to the editor, perhaps you issue is one of them.

 unintentionally is deleted in an e-mail message.
