I am pretty sure everyone knows about this bug already but I couldnt find any official comment on it and it is still present in the WIP built.
When you add a light source, for instance a rectangular light, into a scene where the light is visible through glass it becomes visible as if it is an emission material applied to a surface.
All light sources seem to act this way as well as show up in any reflections as if they are a visible emitting surface.
This only becomes an issue if you are using lights to add extra light in certain places in a project with large amounts of glass like a glass curtain wall.
In the attached pictures you can see where I placed a rectangular light with a glass wall that cuts through the light source showing it is not visible without the glass but appears through the glass and in the reflections. The bottom square has an emitting material placed behind it so I could compare the reflections of an actual visible emitting material and a supposedly invisible light source.
