on a LED that's probably the maximum reverse voltage the manfacurer
guarantees it for, I've seen LEDs witstand as much as 12V (in the reverse
direction) without failing.

it's basically the design limit of the part.
all good parts will exceed the design limit by some extent. those that don't
are often relabled and sold as a less robust part.
