Bone meal glitch

In Minecraft, when you want to grow a tree, crops, pumpkins, etc. faster, you can usually use 2-5 Bone Meal on it to make it grow. But there’s a bug in a recent version of Bedrock Edition where if you use Bone Meal on a tree, crop or anything else, it alwayd fully grows INSTANTLY. In Java Edition, prior to 1.5, using Bone Meal on anything that could be Bone Mealed grew it INSTANTLY, but when Mojang realised it was TOO OVERPOWERED, they added in GROWTH stages. And the same was applied to Pocket Edition Alpha v0.8.0 Build 1. Is this a glitch or an intentional game design? I think it’s a glitch, please fix it if it is.

Thanks for understanding.
