I'm wondering if this solves only the case when the > is not followed by space. I guess the following would interpret a blockquote meanwhile it should close the div, right?

<div
> thing that follows the div, not blockquote
.
<p>
<div
</p>
<blockquote>thing that follows the div, not blockquote</blockquote>

Thanks!

It solves both cases. I've added another regression test for the case where it is followed by a space.

Perfect, merged.
