HTML5 Nesting Issue or SimpleGrid?

Hi there,

I just had a really weird scenario. I had 3 columns set up (col-1-3). I had the <form> tag at the start of the first column and the </form> at the end of the third one.

However browsers decided that the </form> tag should be placed at the end of the first column. I fixed it by defining the form before the 3 columns.

But I'm not sure if this is a Simple Grid issue or just a random HTML5 niggle.

Thanks!
