"unrendered" at page load

[Prinzhorn]

Elements which use data-0 get the unrendered class on page load, even though they shouldn't. Because if you scroll down and up again, it correctly has rendered at 0.

Reopening because it's still wrong for data-end. But priority is lower, because it requires the user to first scroll down to the very end and then refresh the page, which is unlikely.

I'm not able to reproduce it. Maybe I was looking at an old gh-page last time.
