Firefox 47 is supposed to support IDBKeyRange's includes method, but I'm having a hard time understanding why it's giving the results it is giving.
The first value in the Idea is what I'd expect, the second is what FF actually gives.
// These work as I'd expect to retu false
console.log(IDBKeyRange.lowerBound(2).includes(1));
console.log(IDBKeyRange.lowerBound(4).includes(3));
// These do not behave as expected (I'd expect "true")
console.log(IDBKeyRange.lowerBound(1).includes(1)); // FF gives false
console.log(IDBKeyRange.lowerBound(3).includes(4)); // FF gives false
What am I missing here??
