When loading a texture-pack, by dragging and dropping a data pack onto the minecraft texture pack selector window it will prompt you to load the data pack and then you get a data pack in the texture pack menu which is completely bizarre and has no purpose...

To reproduce this:

1. download a datapack
2. open up a world
3. open up the resource pack selector
4. Drag & drop file onto minecraft window
5. Minecraft should prompt you about loading a datapack
6. it appears there :|

maybe this is intended but i don't see why this window would even show datapacks there

the second image shows the items inside the zip datapack I added... you can see clearely there is a data folder (datapack)

even datapacks display their pack.png as shown with one of my datapacks from PMC despite being in wrong folder
