End terrain generation fails with specific seeds

The seeds

7593177223396 (first found), 8994765102493, 32896149644487, 45459229772041, 47874503654705, 75387315386474

Have no spawn end islands, just the obsidian pilasters, the end crystals and the bedrock at the center. This always occurs

This seed has caused this issue since the first introduction of the end in release 1.0, and every version since! Wow!

I can also reproduce using Minecraft 23w51b. Because the exit end portal generates at the floor of the world, the end portal blocks are placed outside of the world bounds, making leaving the dimension without dying impossible.

The outer end islands appear to generate fine, it's only the starting island that is broken.

May relate to MC-93185 in some aspect as it makes overworld return impossible. A workaround could be to always generate a chunk of end stone or such at (0,y,0) in the End such that even if the island fails to generate entirely for some reason, there's still space for the portal to form.

Other seeds which may cause this are 8994765102493, 32896149644487, 45459229772041, 47874503654705, 75387315386474, 95859970597671, 97313882082378, 107922335640096, 119085881159739, 138511680831956, 140346562199561, 151583292858476, 171678328848504, 184638198002278, 203584364303715, 212144309231988, 222026241845411 and 231024143342486. Can someone verify?

This occurs because the ammount of endstone the main island is made of is randomly selected and unrestricted.

Since this got triaged I'd like to say I'd hope Mojang resolves this as WAI or a low cap of like 10k at most is introduced. The related bug MC-93185 does need fixing tho.
These low endstone end seeds are truly stunning and rare sights that I would hate to see removed.
