Taxonomy term pages with image put image at bottom of page for only 1 or 2 items with that term

[bugfolder]

Description of the bug

If we create a taxonomy term with an image field and then give some nodes a term reference field that references that term, on the taxonomy term page, the term image shows incorrectly at the bottom of the page if there are only 1 or 2 nodes with that term, but correctly at the top of the page with 3 or more nodes.

Steps To Reproduce

To reproduce the behavior:

• Create a vocabulary, e.g., "Clothes."
• Add an image field to it. Give the image field a default image.
• Create a new content type.
• Add a term reference field to it.
• Create three nodes of the content type, each of which has the term reference set to the "Clothes" vocabulary.
• Go to the term page for "Clothes". It will show the term image at the top of the list of the 3 nodes, as one would expect.
• Now, for one of the nodes, remove its term reference.
• Revisit the term page for "Clothes." It now puts the term image at the bottom of the list of 2 nodes.

Expected behavior

The term should show up at the top of the list no matter how many nodes there are. Here's three nodes:

And here's two nodes:
