Dropping items by holding down q stops when you press any other button.

When you hold down q(or other drop item key bind)  the items stop dropping after you press an other button like W(walk forward key bind) but if you hold down W and then Q both work at the same time (you walk forward and drop items) which in my opinion is an inconsistency.
Edit:It is also the only action getting canceled(you can jump and throw items for example but only if you first hold down jump and then Q if you do that then it does both at the same time). And if you rebind the W key to Q it still works the same(it stops dropping) so the problem seems to be in the game (not hardware)
