This bug has been bothering me for a while because it is really annoying to me. I am a creative mode builder and love to be very fast with my building but I play on android and will sometimes click on the wrong item, a glitch that I have found is if you select an item/block and then scroll down, you won't be able to select another item unless you either exit the menu or press/click on your inventory (get nothing put into your inventory) the same happens if you have selected an item/block and switch tabs. This bug has probably already been reported but after like half an hour of looking through bug reports (there sure are a lot) I couldn't find anyone mentioning this issue. Sorry if it is a duplicate, just really want it looked at.

The images are hard to tell but basically I select oak wood planks scroll down; then select dark prismarine stairs, spruce doors, and smooth quartz stairs.
