Comment 2 for bug 1953412

I used GOBACK to return to language and entered the dialog again, and it was still blank (devoid of choices)

This was repeat again (GOBACK & CONTINUE) again with no choices.

I used GOBACK to return to languages & this time picked other than the default ENGLISH (which was implied-accepted via CONTINUE and not chosen via mouse/keyboard) then switched language back to ENGLISH and finally I got choices in keyboard layout.

ie. I needed to return to prior screen, select a different language choice (not pressing ENTER/continue), then return to english to make choices appear in keyboard layouts.
