I found a post for exactly the same problem I am experiencing, but it was 4 years ago and no answer was posted.
The report behaves fine when in Report Builder and the headers are fixed, but when deployed to a Report Server the right scroll bar causes the whole report to move, not just the data in the report, so I lose the top ribbon bar and the report headers as well.
