Hello, can this still be reproduced on Chrome Canary?

As per comment # 2 checked on latest chrome canary build.
Able to reproduce the Issue in 57.0.2977.0/9171.0.0 i.e. Using Up/Down/Right/left arrow buttons from keyboard focus does not traverse

tommycli@ - Here is what I see: When the page is opened, we show the focus highlight around the selected image, but the image select is not actually focused. Pressing 'tab' twice will select it at which point the arrow keys work fine.

I can go ahead and look into focusing the image select by default since this is CrOS only, unless you know exactly what it is or want to take this on.

stevenjb@ - Thanks for diving into this.

For your reference, the Manage Profile feature (Chrome Browser) has a similar grid that uses the generic cr_profile_avatar_selector. It's possible this can be adapted to the ChromeOS situation as well, but I didn't do that since there's the Camera, File, and Old Picture icons that complicate things.

Just for your reference...

Ah, thanks. I think I will go ahead and fix this specifically for Settings,
it looks like explicitly focusing the container on navigation will do the
trick.
