Low Superflats create incomplete strongholds

What I expected to happen was...:
Even though I knew this for at least 1.5 months, here's what I think what the stronghold should be. I think that the stronghold should be a complete building in mid-air with some sort of supports if there needs to be supports.

What actually happened was...:
The Stronghold was incomplete, a lot of sections from the stronghold were missing.

Steps to Reproduce:
1. Create a superflat world with strongholds and have a low altitude level. (The second picture has a sample configuration for you to create incomplete strongholds.)
2. Use the Eye of Ender to locate the stronghold.
