Strange behavior when merging stream to properties

[ArseAssassin]

I'm getting strange results when merging an active stream vs. ended stream into properties:

var k = require('kefir')

console.log('Merging property to non-emitting stream')

var s = k.merge([
    k.constant(2).merge(k.later(1000)).toProperty(),
    k.constant(1)
]).toProperty()

s.onValue(console.log) // log: 2
s.offValue(console.log)
s.onValue(console.log) // log: 1
s.offValue(console.log)


console.log('Merging property to ended stream')

var s = k.merge([
    k.constant(2).merge(k.never()).toProperty(),
    k.constant(1)
]).toProperty()

s.onValue(console.log) // log: 1 
s.offValue(console.log)
s.onValue(console.log) // log: 1
s.offValue(console.log)


console.log('Flat merging property to non-emitting stream')

var s = k.merge([
    k.constant(2),
    k.later(1000),
    k.constant(1)
]).toProperty()

s.onValue(console.log) // log: 1
s.offValue(console.log)
s.onValue(console.log) // log: 1
s.offValue(console.log)

I would expect all cases to behave as the last two. Am I missing something here?
