 The emojis show up as browser fingerprinting in several different browser
 extensions.

 The issue lies in `var d=k.toDataURL();` in the script block added by the
 emojis (block starts with `window._wpemojiSettings`).

 Further, and more importantly, firefox is going to start prompting users
 when a page uses several methods associated with canvas fingerprinting
 (ref https://thehackernews.com/2017/10/canvas-browser-fingerprint-
 blocker.html).
