On my side, the put-text-property does have center-line.
But only when buffer is in Org mode.
Yet, it is not Org's fault.

The reason you are seeing the horizontal line is org-link face.
org-link has underline. And the "center" line you are seeing is actually
underline coming from the face. I'd say it is emacs bug.
