SceneCaptureComponent2D's Clip Plane not working?

Hello everyone.
So for a while I was trying to figure out what is wrong with my Portals setup and finally gave up.
It looks like that Clip Plane Base and Normal doesn’t work.
I even took the tutorial on A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums and it still doesn’t work.
It still doesn’t clip what can be seen here .
The funniest thing is I downloaded the project from the wiki and the same thing is happening.
Does something changed between 4.15 and 4.17 in this regard?

So I found this
Planar Reflection OpenGL Clipping Plane Bug - Platform & Builds - Epic Developer Community Forums .
Apparently ClipPlanes never worked in OpenGL4 rendering and unfortunately it is also the case for Vulkan.
The bug is present as far as version 4.12 with is more than a year old.
Can we do something about it?
