When a 'div' is used in a wiki page, it is stripped out by the renderer and replaced with 'p'...'/p'.  The id attribute of the 'div' is lost.

This behaviour may be appropriate for user-entered text, but 'div' is used internally when appending a remark to a Wiki page.

Significance: This ticket is related to feature request [b92c4160fe282a0a121146d1216ec692408b2206] to include a class attribute on appended remarks so that they can be styled independently of the rest of the Wiki page.
