Shulker Box with items does not drop when broken in Creative Mode

Shulker Box with items does not drop when broken in Creative Mode. It used to work, now it doesn't.

Steps to reproduce:
1. Place a Shulker Box
2. Put any items inside the Shulker Box
3. Make sure your gamemode is set to Creative Mode, and then break the Shulker Box

Expected result:
The Shulker Box drops as an item with all stored items inside.

What actually happens:
The Shulker Box disappears.

I was unable to attach the video clip directly due to its size, so here's the link instead: https://drive.google.com/file/d/1hWRPy5Vx3d2dfRDHfch-xVgHbp4hnART/view?usp=sharing I would reccomend turning the volume down or off, as the music did get loud while I was recording.
