Can't get transitioner working

[ffxsam]

Ok, I've got reproducible code:

What am I doing wrong here?

Figured it out. But now there's another issue.

Content is cut off, and it won't scroll:

try position absolute with overflow-y scroll

I was having same problem and was able to resolve with:
.transitioner{overflow-y: scroll}
