Issue with masked materials (Forward rendering + MSAA)

I’m having issues with a masked materials on forward shading and MSAA. All masked materials become translucent. I have no problem with MSAA and deferred rendering.

With MSAA:

With TAA:

You can reproduce it in Material_Properties map (Content Example).
