"Updated" message DIV jumping around Edit Post screen

[Alhadis]

Okay, so I'm developing a plugin that uses a separate form tag on the Edit Posts screen to manage custom attributes. This form's inserted into the header using the "in_admin_header" action.

Now, to keep the same consistent formatting, I've used the same class names as used by the headings on the rest of the page:

<div class="wrap rbs_ep">
	<div class="icon32"><br /></div>
	<h2>Edit Properties</h2>
	
	...
</div>

Now, whenever the page is published or updated, the "Updated" message box suddenly jumps from the top of the page into the form. Looking through the source for a bit, I found the culprit:

./wp-admin/js/common.dev :: Lines 197-199

// Move .updated and .error alert boxes. Don't move boxes designed to be inline.
$('div.wrap h2:first').nextAll('div.updated, div.error').addClass('below-h2');
$('div.updated, div.error').not('.below-h2, .inline').insertAfter( $('div.wrap h2:first') );

This little script is assuming that the first <h2> tag it finds is the one being displayed at the top of the page to the user. Now, I know the obvious solution here would simply be to move the form's source to the page's footer, but I still think this is a clumsy solution to an otherwise preventable issue.

Can't the Edit Page's heading be assigned an ID so the script can place the "updated" box more accurately? I don't want to duplicate CSS rules in my layout simply to reapply the same formatting using a different tag (e.g., "<div class="h2">Edit Properties</div>"), as this'd simply be a messier approach. I think the script should be looking for a H2 tag with an ID (or at least a specific CSS class) to place the message box.

There's not much we can do here, because we want the UI of plugins to be in line wiht core, and authors have the expectation that <div class="wrap"><h2>Title</h2> ... </div> will simply work. It's not just about changing core.

It would take very little for your formatting to not conflict with this. You're using a thickbox popup anyway, so you can either change the wrap class, use an h3, rearrange the form orders, or something. Using an h2 is designed for a page title only, not a section title in a popup like this.
