PC XP from crafting, bug or feature?

[warmer]

I just noticed I don't receive XP from making ammo if I am not "in" the workbench menu. 

If I am out of the workbench menu, the XP gain stops.
Then I go back in, and it starts again.

Is this a bug or feature?

If it is a feature, then am I gaining speed by being in the workbench menu, or just XP?
Out of the menu, the items are still getting crafted, so I am not sure what is going on.

I might be mistaken but it was like that for a long time... so feature?

I don't know if I'd call a feature, but it's been that way for ages .. we used to craft anvils on several forges to increase tool crafting, swapping between them to have the right one open when that specific anvil was about to complete for the (skill) XP. Queue a new one, move the newly made into the melting slot, open the next forge... better than trying to destroy stone axes, but quite riveting gameplay nonetheless..

Does it increase the speed or just the XP?

It doesn't* affect the crafting time.

*shouldn't, edge cases like the short-craft nails might suffer from lag issues with the UI open.
