I also repro this with the Lenovo Explorer with a Surface Book 2. This bug is game breaking.

I have noticed the same thing and this issues makes it take a bit longer to divide your material and distribute it into multiple furnaces.

For example:
I have a stack of 40 iron ore and want to put it into 4 furnaces.
Split it in my inventory into stacks of 10
Open the first furnace
Select a stack of 10 in inventory
Hit button for move all (Y on my controller)

Result:
I now have a stack of 20, 10, 10 in my inventory and noting in the furnace

Expected:
Stack of 10 should have gone to the furnace

This seems like it just changed recently. I can repro on xbox and pc. I find that it places blocks so fast that I wind up taking damage from them if I am moving and trying to place a row of bricks. It also makes trying to open / close doors annoying.
