[wiki] The "Article history" interface uses invalid HTML (same id attribute for multiple elements)

The page (http://qt-project.org/wiki/diff/<ArticleName>) you get to when clicking the "Article history" link in the sidebar of any wiki Article, contains a section of the following form for each listed revision of the article:

<div class="itempad">
	<input name="rad_revision1" id="rad_revision1" ...>
	<input name="rad_revision2" id="rad_revision2" ...>
	...
	<input id="rev1_id" ...>
	<input id="rev2_id" ...>
</div>

The exact same four id's ("rad_revision1", "rad_revision2", "rev1_id", "rev2_id") are used in all such sections on the same page.

This is expressly forbidden by the HTML standard - the value of an id attribute must be a unique identifier for a single element.

Either the server-side script should generate a unique id for each of the input elements, or (probably a lot easier) the client-side JavaScript code that operates on them should not address them by id, but rather by class or name (which are allowed to be the same for multiple elements).
