(low priority) shouldn't body.header not scroll with the sections?

The docs seems to imply that the sections are scrollable but the body.header should not. With a templates/body/header containing a search box scrolling the templates/body/sections[0]/items causes the search box also to scroll.

If this is as-designed then please just close, if this strikes you as not what's intended then I will provide a jasonbase test case from my app.

Start with the documented templates/body/header and templates/body/sections[0]/items behavior described in the issue; no file, entry point, or test case is provided. Reproduce whether scrolling the sections moves the header search box, then confirm the intended behavior with maintainers. Done means the behavior is clarified and corrected if it is not by design.
