Regression: Nested signed mail showed as nameless.eml

[minimalisticMe]

Describe the bug When extracting a mail with multiple nested mails (mail attachments) I can extract all mails correctly, but one mail is named incorrectly. One of the attached mails is a singed mail and the name of this mail is "Nameless.eml" instead of the correct name. This was working correctly on a prior version (I am not sure which one, it was some time mid last year).

Platform (please complete the following information):

• OS: Windows 11
• .NET Framework: .NET 8
• MsgReader Version: 5.5.5

Exception No exception, just incorrect parsing.

To Reproduce Is there a way to share the mail securely? It contains personal data of me.

Expected behavior The name of the attached signed mail is read correctly.

Code Snippets

var eml = MsgReader.Mime.Message.Load(stream);
foreach (var item in eml.Attachments)
{
     if (item.IsAttachment)
     {
         var originalFilename = item.FileName; // wrong in one of the attachments
     }
}
