While sorting the TableView the focus ring was in the incorrect
spot. Upon investigation, the position was always the model_index
instead of the view_index.

Added a unit test to make sure that the active row index matches
the view index being shown meanwhile the model index differs (which
tells us it has been sorted). Previously this test will fail since
the focus ring is being rendered in a different position.

AX-Relnotes: A focus ring now appears around the correct cell
in tables that are found in e.g. Chromium's Task Manager.
