What's the problem? Describe what went wrong in few words.

On Bowser's Dark Matter Factory, when the gravity flips from upward to leftward, on Dolphin you can clip through the wall and die unless you jump away. On Wii, while you do jitter and sorta clip into the wall, it never lets you through.

What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]

1. Go to Bowser's Dark Matter Factory (Final Stage of Galaxy 4)
2. Just stand on the spot demonstrated in the video before the gravity switch
3. Transmute time and space as you gain the ability to walk through walls.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?

4.0-1342, 4.0.2, 3.5; all were afflicted with this problem.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)

Core i5 3570K, GTX 760, Windows 7 64bit

Are you using the 32 or the 64 bit version of Dolphin?

64 bit

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

I tested JIT and JITIL, and am in the long process of confirming this problem happens in interpreter; expect a comment once I'm sure.
