Skelleton trap turns invisible once you die

When I had a bunch of skeleton trap horses around, and then I died, they were still shooting, but they were invisible.

What I expected to happen was that they would stay visible and keep killing me

What actually happened was they turned invisible and started shooting me

Steps to Reproduce:
1. Make a normal Superflat world (that is just were I was, may work on normal worlds to)
2. Summon a bunch of skeleton traps
3. Go into survival and die to them (I could only make a video for that, i could not get a screenshot)
