System Information
Operating system: Windows 10
Graphics card: NVIDIA Quadro K600

Blender Version
Broken: 2.80 official
Worked: (optional)

Short description of error
after applying Remesh modifier with mode as Block, the result object has non-manifold edges.
the blocks of issue are sharing only edges instead of faces and make non-manifold edges.
its rough sketch looks as below:

  |-----|
  |     |
  |-----x-----|
        |     |
        |-----|

where non-manifold edge is marked as x

I am not sure if this behavior is a bug or not but I guess this behavior could be avoided by inspecting shared edge and face or something.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

I can confirm this issue. It would be nice if you could create a simpler file that reproduces the issue. Fixing this probably requires some deeper changes to the remeshing algorithm. Maybe this should be put into the known issue category, I'm not sure..

Would consider this as known issue, that’s not really a bug in itself, almost more like a feature request actually. ;)
