Expected Result:

Keyboard focus should move on ‘Show code’ button after ‘Select a channel’ combo edit box using Tab navigation.

User Impact:
Keyboard dependent user will have difficulty in navigating, when focus order does not follow the visible reading order, the experience can create a different interaction pattern, and/or unintended content relationships for assistive technology users. On rare occasions, there is a logical reason the focus order is different from the reading order, but the meaning of the content and interactions must remain the same.
