TransitionsEnabled=false NullpointerException

[tomerdomshlak]

What steps will reproduce this issue?

Create a MetroTabControl with 2 tab items, each of them is a MetroContentControl.
Set only the first tab's TransitionEnabled property to "false" is fine, but when setting it "false" for the second - a null reference exception is being thrown.

I'm trying to get rid of the animation for both tab's contents, because it doesn't look well with my color scheme.

Thanks, very much appreciated.
