Sequencing in UI Pack doesn't work on display: none if not the last item

[AlexeyGorokhov]

animSequence = [
// Hide the spinner
{
e: $spinner,
p: { opacity: 0 },
o: {
duration: 150,
display: "none"
}
},
// Show the button
{
e: $btn,
p: { opacity: 1 },
o: {
duration: 150,
visibility: "visible"
}
}
];
$.Velocity.RunSequence(animSequence);

The spinner won't get display: none. Although, if it goes after the button, everything works correctly.
