mi: ensure chained button mappings from SD -> MD (#19282)
After copying the master event, flip the detail field to the mapped button of
the SD, not the physical button. This way if the SD has a mapping 1:3 and the
MD has a mapping of 3:4, a press on button 1 on the SD results in a core event
on button 4.
