First at all, sorry if this is a repost. I searched and couldn't find anything similar. The old method consists of walljumping the invisible box. This is kind of showoff. Since walljump doesn't work anymore, its still possible with mage blink.
Aim here and blink:
Have fun messing
How it works:
Sometimes you get a bit pulled back when you blink with an object in front of you (like that brazier). So i managed to find the position to step inside of the platform. And yes, it can work with the other platforms if you find the right spot.
