When you spec the two nodes in Healing Hands tree “Unbroken Prayer” (which makes the spell a channeled spell which is is casted 4 times per second) and “Homeward” (which makes the the spell not casted at your cursor but always centered to your character) that skill is still centered to your character but stops channeling.
None of those two nodes is telling that they should not work together. So it seems to be a bug? Or it is intended and just not mentioned in the tooltips?
