That doesn't make sense since this also occurs in the launcher and on minecraft.net.

Was able to replicate in 19w11b.

It was done in a Superflat world. After following your steps (the command was irrelevant), I was still unable to replicate the issue.

I can't seem to reproduce the issue.

Seems to work fine for me.

My friend seems to experience no issues on 1.2.6.

Please refrain from making duplicate comments.

I doubt that split view would be needed at all, as your main focus would be on Minecraft and not whatever it's being split with.

The screenshots depict dark oak wood planks, not oak wood planks. What is the issue here?

Try it again on a different console, if you can. My original Xbox can manage a Realm with three other players.

Did you have the cats sit? All tamed mobs teleport to you if you go far enough away and they are not sitting down.
