Hotkey does not update radio button focus #128

I have a simple Likert scale displayed using radio buttons, with autofocus on the middle button:

If I use the arrow keys to select a different radio button, the focus moves with the selection:

However, if I use a hotkey, the selection changes but the focus remains on the original button:

Is this the desired behaviour? The radio button test only mentions activating radio buttons, not focusing them, but I expected that a hotkey would behave the same as using the built-in keyboard navigation (tab, arrows).
