Stair Rails 'Popping' through Walls and Windows (Patch 1.73)

It seems like some stair rails have a wider footprint than the walls, these will show through walls. The same goes for some stairs (the snowy escape ones as one example). My solution so far has been not to use these stairs or rails when placing a staircase next to a wall but that doesn't seem like a reasonable solution. 

What I'd love is the ability to only use rails on one side of the stair...
