ENYO-457: Header: Focus Does Not Display in Input after 5way

### Issue:
ENYO-457 and BHV-14227 both seem to to result from BHV-10720, which, when input loses the focus, unspots the input decorator based on the pointer mode. The initial issue, BHV-10720, seems to be a very minor issue, so I think this code unspotting the input decorator should be removed.
### Fix:
Remove the code which unspots the input decorator when the input loses focus
