Hotmail CSS leakage

Safely embedding one HTML document in another isn't easy.

Normally, at the bottom of a reasonably long message, Hotmail displays these buttons and links (with my mouse hovering over the Delete button):

But one piece of HTML email I looked at this morning caused this (again with the mouse pointer over the Delete button):

It appears that the style rules used by the HTML email have "leaked" out to affect the Hotmail web page itself. What Hotmail should be doing, I suppose, is rewriting the email's style rules so that they are only applied to the email and not the Hotmail page around it, but that would probably be painful and error-prone. Even so, you could accidentally or intentionally make a real mess out of the Hotmail page if you exploited this; it might be possible, for example, to make the Delete button disappear.
