Signature turns out to be quote after a reply sent

[bash-horatio]

Are there any related issues?

#1895 also about signature, but my problem is different from meismyles's.

What operating system are you using?

I have two computers, system of which are Debian Testing and Debian Stable .

What version of N1 are you using?

The same problem in both nylas 0.4.16 and 0.4.25

Bug?

Do you have any third-party plugins installed?

I didn' t install any third-party plugins at all.

Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

Signature set on Gmail works perfectly. The one set on nylas works well when emails are sent at the first time, but turns out to be quote texts when replying to others.

Is the issue reproducible with a particular attachment, message, signature, etc?

My signature set on nylas is something like this:

A reply sent from nylas:

Email show on Gmail page:

quote text:

Feature Request?

Does this feature exist in another mail client or tool you use?

I don't have much idea actually since I used to write and receive email just on Gmail website.
I think email client like ThunderBird are awful(at least not suitable for me), but nylas gave me an awesome impression when I had a glance at its UI and design.

Could you post the raw HTML from Gmail? It is more helpful than a screenshot in this case.

Sorry, I don't know much about html, and simply upload the codes and forged/replaced some private information.
In conclusion, The problem is that signature works in first email sent from n1, but became quotes when replied.
"n1-signature.html" is my signature set in n1. "sent-relpy.html" is html code of this two test emails on Gmail.
