Gatsby emoji are not displaying properly

For example here, gatsby's emoji are not displaying properly.

Maybe we can select these emojis based on their attributes and apply max-width.

In fact, every emojis are not displayed properly just now 😆
The reason is most of the emojis rendered here as an image and it does not have a specific class name or anything to indicate it's an inline emoji. At first, I thought we could just limit the size for any inline image that appeared in a <p> tag, but not sure if there is any other cases.
