I've filled MC-146817 but I'll describe here what I was doing.
First time it happened I was breaking oak wood slabs from bellow with an enchanted diamond axe. I repeated this several times.
I then joined the game and did some other stuff. It all worked. I've broken more oak slabs but more slowly and it worked.
I felt confident, I started to break spruce logs quite fast and it happened again. It might be related to the speed of breaking, or the fact that I broke several things without releasing the action button (my 2 ct)
