Simplified email threading - Make images render in the email thread history

Feature Request Summary: 

When using Simplified Email Threading the images in the history should render. This is how it looks today from Microsoft Outlook from customer side:

Description/Use Cases: 

We work mainly with email as our main channel for customer communication, when our customers loop in colleagues etc. they won't get the full mail history and miss screenshots etc. that will help in understanding what the ticket is about.

Business impact of limitation or missing feature:

This impacts our customer support experience negatively as all information about a ticket is not included in the thread history.

Other necessary information or resources:

I opened a ticket in support, and I got it confirmed from Zendesk that Simplified Email Threading currently does not support inline image previewing in an email thread.

Hopefully others that would benefit from this could share their stories and maybe even there are some ways of working around it that we could share here.

Thanks in advance!
