The Bug:

The pick block function doesn't work with entities while in survival or adventure mode.

Using the pick block function on a block in survival or adventure mode would switch your hotbar selection to that block if you have it present in your inventory. This isn't the case for entities such as item frames, boats, paintings, minecarts, armor stands, end crystals, etc...

Steps to Reproduce:

1. Obtain two item frames and switch into survival mode.
2. Place one of them down and begin holding anything other than the item frame in your inventory.
3. Use the pick block function whilst looking at the item frame you just placed.
4. Take note as to whether or not the pick block function works with entities while in survival or adventure mode.

Observed Behavior:

The pick block function doesn't work.

Expected Behavior:

The pick block function would work.
