HUD Issue for 20w21a

I was recently playing the latest version of Minecraft, 1.16 snapshot 20w21a. I was playing like normal and then I noticed a HUD issue with numbers popping out of the text box for item names. For example, If you were to hover over the item "Dirt" the text box would appear. However, if you had a stacked item where the gray text box is, the number would layer in front of the text box.
