Why didn't Héctor fade away after this character died in the movie Coco?

In the movie Coco, a person in the land of the dead will fade away completely when no one from the land of the living remembers him anymore, and that is how Héctor’s friend Chicharrón faded away, because there was not one person left in the land of the living who remembered him.

Later, Miguel tells Héctor, when they are in the pit, that he will go the living World and remember him and that is how he won’t fade away, but Héctor clears up that is not how it works while Miguel notes that Coco won’t be able to see Héctor when she dies.

Miguel returns home, helps Coco remember her Papa, and she does, she then gives him Héctor’s photo as well, and they put it up for next years festival and we find out that Coco died.

Now, no-one is left in the living world who remembers Héctor, Coco died and is not part of the living world, however, we see that Héctor has still not faded away.

Am I missing something from the movie or is this really a loophole in the plot?
