Snaptooth Seedlings behave strangely when they eat meat at the moment they're killed

I haven't managed to get a screenshot of it, but I've noticed that when a Snaptooth Seedling eats meat and grows to the next stage immediately as I kill it, sometimes it survives in its larger form but still plays the death animation before the growth animation and sometimes it grows and then immediately dies. It's awkward to watch, although the results aren't mechanically different from if it ate the meat a little earlier.
