Regeneration heart graphical bug

What I thought was going to happen:
The "wave" of hearts should finish and stop

What happened was:
A heart got stuck in a "up" position

Steps to Reproduce:
1. Eat a Golden Apple/drink a Regeneration Potion.
2. Wait for the regeneration to wear off.

Photo provided to show the graphical glitch. If you get regeneration, the hearts go in sort of a wave pattern, yes? Commonly, when the regeneration ends, a heart is locked in a sort of ''up'' position.
