Making emojis in the "Reactions" (as well as the {+} button) selectable via arrow keys and have the first one autofocused/selected

[Johannes5]

I'm considering using your emoji-picker-react component in an app.

I want it to be in "reactions-mode" per default.
(and I feed the reacitons prop with a specific selection of emojis)

What I haven't been able to do is to make sure that the first emoji (of those "reactions") is highlighted. And that I can highlight the adjacent emojis with the arrow keys.
This only seems to be working when the picker is expanded.
