No Exp when hotbar crafting

Game mode: Online - Official Server
Problem: Bug
Region: [Here]

As far as i can tell this is gamewide. When you have a building item in your hotbar and you press it to craft you do not get the EXP, only if you inventory craft it.

Here is an example video i made, watch the EXP bar between the 2 crafts: (Links were not allowed)

Iv tested it with blackice items and a few others, it seems to be all items.
