Baby bunnies and possible other baby mobs dissapear from short distance

Basically its just what it says, baby bunnies dissapear from view getting not far from them, however seems that big bunnies can be seen from quite far as usual. I havent tested but it may be the case with other mobs or their baby forms as well. I added two screenshots.
Bunny in further photo is the same adult bunny as in first one. but baby bunny doesnt show up even though he is here. I even got back and forth to make sure baby bunny is here and yes it reappears as soon as i get closer again.
