When I when to build a zombie pigman farm on the nether roof  I realised that I couldn't place blocks as the height limit for building is 128 blocks not 256 like it is in the overworld. Please fix this as the Java edition players can build on the nether roof but the mcpe players cannot.

To recreate this go to the roof of the nether (on top of the bedrock) and try to place a block in mcpe.
I am using an amazon fire 08 tablet to gain access to the bedrock edition of minecraft.
