@timtorChen only the recent emojis/search results, or the content of the categories as well?

The search result and the content are both blank tiles.

I have been trying to triage this issue for some time.
I can select an emoji and it copies. I can paste it to firefox, chrome, franz, and libreoffice and they work. I can't paste them in gnome products like terminal, text-editor, and any other gnome things. I can paste them. They are there, but they just don't visually show.
To me, this is more a gnome font issue and not an issue with this wonderful extension.
