Furnace infinite XP bug

You can collect infinite amounts of exp from a furnace by taking 1-64 blocks everytime and go quickly from lvl 0 to 30 in my opinion the furnaces don't recognize you took the item and every time gives alot of xp.

Experienced that on my automatic smelter each time i take out 1cobblestone it gives me like 14 levels which results getting level 100 in a few minutes i did some research and people have this issue in singleplayer bedrock edition 1.16 aswell. 

The furnaces i used have smelted like 3stacks of iron and gold i thought it stored so much becouse it was my 1st time trying to repair my mending tools but i was able to get big amounts of exp infinite times which really ruined fun of grinding for me and i think other people hoping for a fix in 1.17 thanks!
