FIX: clicking "more..." in emoji autocomplete (#26176)

This reverts the "fix" made in 44f6b24e34 since it wasn't the correct fix and the emoji picker wasn't showing in chat 🤦‍♂️

The proper fix is to `stopPropagation()` on the `click` event since the click handler has been made `async`. `preventDefault()` isn't enough.
