BB Text Editor removing anchor tags

Hi,

I’m using anchor tags in the BB text editor, and because anchor tags tend to be somewhat inexact, I’ve gone with the approach of putting the anchor above the heading I want to link to. So instead of <h1 id="anchor">Some title</h1> I’m going with <span id="anchor"></span><h1>Some title</h1"> I’ve also tried <a id="anchor"></a> and even wrapped the <h1> in the span and before you ask, yes I’ve also put a non breaking space between the span and anchor tags to see if that was the problem. Each approach works until I reengage the editor. As soon as I go in to the page to edit it again, all the anchor tags are replaced with a non breaking space. I don’t understand this behavior.
