Fix custom emoji reactions in topics

When using the custom WoP emojis to either react to a topic or a topic entry, the custom emoji will not be displayed. Instead, the text ‘Array’ will be displayed. This applies to all custom emojis.

Even when clicking on ‘Array’, the emoji will still be displayed as ‘Array’. However, you can see who reacted.

Please fix this to display the custom emojis instead of the Array text.
