Site auto-updated to version 6.6.2 and emojis are now GIGANTIC

Sometimes, updates can alter CSS rules. Inspect the emoji elements using the browser’s developer tools (right-click on the emoji and select “Inspect”) and see if there are any font-size or line-height rules being applied that could be causing the large size. If you find any, you can override them by adding custom CSS.

For example

img.emoji {
font-size: inherit !important;
width: auto !important;
height: auto !important;
}
