Looks like Safari completely ignores the imagemap at http://alt.ngs.noaa.gov/katrina/KATRINA0000.HTM Might be related to bug 4788.
Confirmed in 9/2 ToT; works fine in 412.2.2
For some reason, we no longer are willing to create <area> elements as children of <div> elements. I presume this regression was caused by the qualified name change.
This was broken when we redid the HTML parser as part of the qualified name work.
