The bug

When you get fire and when you jump, you touch it, you will have a jump boost and you can jump over fences (1.5 blocks).

I would imagine this is intentional, as fire and other forms of knockback do push you upwards. Though it can be exploited to jump higher, the entire functionality of knockback is to knock you back... I think this is just a side effect of an intended feature.

If you time it right, you can even jump 2 Blocks high...

@unknown I've made you the reporter of this ticket so that you can change affected versions yourself. Please keep it updated.

This could also be marked as working as intended, but if we ever "fix" this because we change damage knockbacks, I don't want the opposite to be reported as a bug.
