Attachement not visible in Sent email

When sending email with an email (.eml) as attachement, the sent email only shows a paperclip, but the attachment itself is not visible and cannot be ‘found’ nor opened. It only becomes visible when eg. doing a forward of the sent email.
Is this a bug or intented functionality ?
Thanks
Note: ohter file types as attachement no problems.

I can’t replicate the problem on my own computer. Maybe trying upgrading to the latest release and see if that fixes it?
