It's not at all clear to me why this fixes the problem you're having.

The comment here needs to be filled out to describe precisely what this is doing
and why it should be here, as well as why having Instant set the transition type
correctly itself doesn't make sense, and how the proper transition type is going
to be set after this.

Also, don't refer to bugs in comments.  The comment should tell the reader
everything they need to know.
