[FIXED] Stair Rails "Popping" through Walls and Windows

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.55.105.1020
What expansions, game packs, and stuff packs do you have installed? Cats & Dogs, Seasons, Get to Work, Outdoor Retreat, Cool Kitchen Stuff
Steps: How can we find the bug ourselves? - Place stairs on a patio - Put a railing on the stairs (any railing) - On the side of the stairs, add a fence. (As long as the stairs are sideways against a fence, you will see clipping)
What happens when the bug occurs? The stair railing is visible through the fence. It can also be seen when stairs are against a roof piece (shown in the third screenshot).
What do you expect to see? The railing shouldn't clip into a fence. It should recognize there is a fence and disappear so only the fence is visible. It also shouldn't clip into roof pieces.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

I don't know if this is a bug or not, but here you can see the way that stair railings clip:

The third example seems like a visual glitch with the gabled roof.
