Closing as by design. The platform behavior has to have small ranges of tolerances to work correctly. This means occasionally it will "snap" over a small distance, but if we turn it off or even reduce it much, we get other bug reports about other edge cases where the player falls to their death, which is a much more serious problem so we'd rather leave it like this.

Forgive me for necro-ing this post, but I found a workaround for this using a collision detector.

Here's the CAPX:

and here it is in action:

This is definitely not a bug, it's by design. I wonder if it might be rectified if the JumpThru behavior could be told to check which side of the platform the player is entering from.
