Jetpack Newsletter: Social Icons from Social Icons Block not Appearing Correctly in Newsletter Emails

### Impacted plugin

Jetpack

### Quick summary

## Summary

I received a user request for adding social media icons to their Newsletter emails. I tested this on my site without connected socials, only including a link to the socials in the Social Icons block, like this:


Here's what was displayed in each test email when I had the following styles selected:

**Default**

**Pill Shape**


**Logos Only**


Another HE tried replicating it on their test site, this time with connected socials, and the icons were displayed as a bulleted list of hyperlinks:


Both blogs tested with the "Full Text" option selected in the Newsletter settings.

No files, tests, or entry points are named. Reproduce the issue with the Social Icons block in a Jetpack Newsletter using the Full Text setting and compare the Default, Pill Shape, and Logos Only outputs; done means the selected icons render correctly in the email rather than as broken images or bulleted hyperlinks.
