Prototype 1.5.1.1 and Insertion.After

This probably comes as old news to people who use prototype a lot, but I came across a bug with Insertion.After in IE 7.
Is it really any shock that it wasn't working? Seriously. IE.

I didn't spend a whole lot of time looking into what specifically was borked. All I know is that Insertion.After appeared to be doing an insert, but not exactly after.

I decided to just drop prototype 1.6 into the project to see if it fixed the issue and it did. Now I just need to go figure out what changed between 1.5 and 1.6, followed by regression testing of my application.

Fun Stuff. O that the browser manufacturers could agree about how things should be implemented.
