7 bake normal map

Event Timeline

Here are test files for 2.79 and 2.80. Both cubes have auto smooth at 30 degrees. If you press bake you can see that results are different. 2.80 bakes normal map as if it tried to transfer normals from smooth version of the cube onto the sharp one. Exact same thing happens with edge split modifier.

I think this might be related to T61912, but I'm unsure.
