Sharing: Mismatch in "Official buttons" preview on backend and ones on actual page

[arunsathiya]

Steps to reproduce

• Start with a WordPress.com site or a self-hosted WordPress (WordPress.org) site with Jetpack installed, activated and setup
• Ensure Sharing module is enabled
• Visit Settings > Sharing on /wp-admin dashboard
• Enable a few services
• Be sure to choose Official buttons mode

What is expected

The Live preview buttons shown on this page (backend) matches the ones shown on the actual page on the frontend

What happens instead

The buttons are not the same for a few services

Screenshots

The one below is from /wp-admin dashboard

The one below is from the actual page

Notes

The buttons on https://wordpress.com/sharing/buttons matches the ones on the actual page though.

The buttons match fine for other three modes:

• Icon + text
• Icon only
• Text only

I stumbled upon this when I was testing #8883 and from what I see, there is no previous report.
