Unable to keyboard navigate to view a "hover over" on an emoji reaction on chat

We received the following from one of our users.

I just noticed that I got some emoji reactions on my answer on q question on The Club. I tried to figure out who reacted and in which way. I could not navigate to the Plus with my keyboard. Even the search function failed (Ctrl+F). This happens with Firefox and Edge on Windows 10.

I’ve just tried it myself and it is possible to keyboard tab the focus to an emoji reaction (on macOS Chrome Version 110.0.5481.100). Yet the hover-over doesn’t work i.e. it doesn’t show who shared the reaction like it does when you hover over with a mouse.

It’s possible to add the same reaction by selecting enter on the keyboard.

It would be good to have a keyboard-only way to see who reacted to a chat post.
