Feeding does not consume food item but still restores hunger

I noticed that sometimes when you eat something, it isn't consumed at all but still restores your hunger meter.
I also saw that I'm not the only one who noticed this issue, but the last post about it was made in 2016 and seems it's still happening. Is this a game mechanic...?

I made a video to show exactly what happens and how it happens (to me at least).

I'm not using any mods and playing on Windows 10.
