Raycaster.firstHitOnly is missing a closest raycast

[gkjohnson]

When testing the "coffeemat" model there's a section where the closest hit is not retrieved when raycast.firstHitOnly === true:

Specifically on this handle thing:

These are the distance differences when using firstHitOnly = false vs true:

TODO

• [x] Adjust the raycast.html example to repro the issue every time
• [ ] Track down the issue
• [ ] Make minimum repro case
• [ ] Add test

NOTES

• Seems to be related to the leftToRight bounds order check. Inverting it yields correct result
• Also setting isOutside to always be false fixe the issue, as well.

The issue is that this point being used to determine whether to run the next sibling is in world space rather than local space like the bounds:
