ray.intersectsMesh doesnt hit mesh if scaled

Hi, I've been using ray.intersectsMesh when it came with 2.5 and I started noticing in some cases that it doesn't hit the mesh it should intersect with.

Here's a playground illustrating the issue:
http://playground.babylonjs.com/#1IOFE4#9

In that playground I also wrote overwrote the intersectsMesh function that will hit the 2 cases I had where it doesn't hit the scaled mesh if you uncomment the line:

//overwriteIntersectsMesh();

I could be using the ray.intersectsMesh wrong but the way I've been using it is:
direction = mesh.position - point
origin = point
length = direction.length() before normalizing
