I shift-clicked a stack of copper (edit: same happened with copper cable) into an Assembling Machine 1 with less space than available than for the stack I was shift-clicking.
The stack reached (104) in the Assembling Machine and filtered back down (it had ingredients for the item it was crafting)

Screenshot below for second scenario, unaltered

Hello, it is not a bug, the stacks in the assembling machine can actually hold more than a stack.

By 4... I didn't know that, thanks for telling me I just thought it was a bit wierd

It's designed so that you can craft in an assembling machine items needing more that the size of a stack of a given item. For example imagine you need to build ... a satellite ! Needs 100 solar panels, but they only stack to 50. Without that, your recipe would not be buildable in an assembling machine.
