Description
Hello,
here a two pictures which describe my issue:
First picture shows initial state of my table:

When user starts to scroll, the header also scrolls and disappears up to half of the height.


I suppose a scroll-calculation issue. Can you please help me to solve this issue? I upgraded from an ember-table pre 2.0 commit.
kind regards and thank you!

Research direction
The report names no files, tests, or entry points, and provides only screenshots of the table during scrolling. Start by reproducing the header movement in the current ember-table version and trace the table's scroll handling. Done means the header no longer disappears by up to half its height during the initial scroll.
