emojis showing up huge!

I really like this plugin. It used to work normally. But now, for some reason, when I click on an emoji in the comment form it pastes an image that is larger than the size of my comment box. The emojis are huge!
I’d like to keep using this plugin, so any ideas on how to fix this? Thanks!
