Hi,
march Cu didn’t solved the issue.
fromout of Word/excel/… save as has no scroll bar when accessing SharePoint through the URL.
if we use WebDAV, it works correctly.
I support Microsoft is aware of the issue, because we’re not the only one with the problem.

hopefully this will be solved in a next CU.
regards,
Tim
