Datagrid with fixed multi-line header - inline filters scrolling ontop of header

[nicolajb23]

Describe the bug
The header row is being covered over by the inline filter row.

To Reproduce
Steps to reproduce the behavior:

1. Create a datagrid with long headers so that they wrap (making the header taller), using the inline filter, set Fixed to Header or All
2. Add enough data that the scroll bar is visible
3. Scroll down
4. See error (filter row moves up, partially covering the header row)
