Food will continuously go down when holding/clicking right-click on a tamed/untamed horse which is on its "love mode" cooldown.

The food initially starts giving off green particles (untamed) with the chewing sound effect however both particles and sound go away after about 2 seconds (as shown after the baby horse has matured). The same problem is also present when an adult horse has already been tamed after they enter love mode.

I am unsure if this is an intended feature however it can be frustrating losing out on food when the player is unsure if the "love mode' cooldown is over.

THE EFFECT OF THE ERROR IS STILL PRESENT AFTER RESTARTING THE GAME AS WELL SO THIS IS NOT JUST A VISUAL GLITCH 

*This only affects survival mode as creative mode does not expend food when taming/breeding

*Same issue experienced in realms 

*Note: the first two horse were already tamed

HOW TO REPRODUCE 

/summon Minecraft:horse

/give @p Minecraft:golden_carrot 64

proceed to feed the horse until carrots are drained
