dissapearing playermodel after world height

While experimenting with the elytra wings I flew past build height (265 blocks) for a longer glide while F5ed. Strangely the playermodel glitched out and dissapeared entirely. I tried both F5 renditions ( looking at your player from behind and looking at your player from the front). In both cases the playermodel is just gone. pictures of both F5 renditions are attached
