Different behavior between VS and IE in rendering reports with fixed headers and a document map

I apologize in advance if this is something already addressed elsewhere (if so - please point me in that direction).

I have created a really simple report that allows 'drill-down' at the group level. To this report I also selected the 'Repeat header rows on each page' and 'Header should remain visible while scrolling' features and all worked as expected after deploying.

I then added a Document Map referencing the group level and that too worked within the VS environment. VS displayed a page that contained the requested group in plain view and I could 'drill down' as expected.

But when I deployed the report and subsequently pulled it up in IE I noticed a slightly different behavior in that when selecting an entry from the document map, the start of that group got hidden behind the fixed header such that what was visible was perhaps 1 or 2 group records down. I had to scroll up to see the start of the group I had selected from the document map and then drill down from there.

Removing both the "Repeat header..." and "Header should remain ...." allows me to select a group from the document map (which is always at the top) - but in doing so I lose the fixed header feature.

Does anyone have any ideas what I am doing wrong?

I am experiencing this same problem as well. I would also like to know if there is a fix or workaround to this.
