Item count displaying above tooltip

In the latest snapshot, the number indicating the number of items in the stack is being rendered above item tooltips in the inventory. See picture below. I tried restarting the game and the issue persisted. Unknown if this is in any previous snapshots, however I know it did not occur in 1.15.2.
