Front wheel well plastic question?

[dogsridewith]

On both sides of my 07 hatch, the plastic is outside the metal fender where the 4 clips are (3 behind wheel, one above). But the plastic edge is otherwise hidden inside the fender. (An inch or so of gap shows just behind where the plastic liner edge has been relieved to go around the bumper-to-fender clip...and if the liner were to shrink a bit or deform, the whole upper edge of the liner would probably pop out from there back around to the 3 clips.)
