In dark theme selection is hidden by mousehover brush

In sample app -> Grids -> Folder Browser mouse hover C:\, notice the mouse hover brush is brighter than the selection color of "This PC". Now click on C:\, you will notice the background color changes to the selection color without moving the cursor.

Now click on "Theme -> standard themes -> dark", repeat steps above. You will notice the background color of mouse hover (light gray) does NOT change to the selection color (blue).
