MultiGrid header misaligned horizontally and vertically at max scroll for grid
What is the current behavior?
When using the MultiGrid with AutoSizer and a grid that scrolls, when scrolling to the end of the grid the columns and rows in the header grids become misaligned. Looking at the code, an extra div element should be appended to the header to account for the space for the vertical scrollbars; this is missing. The onScrollbarPresenceChange handler also isn't invoked on the initial render when this fails, but on the computers where it doesn't it always is.
It doesn't appear to be an issue with custom scrollbars; the same issue occurs even when using normal ones. Annoyingly this is only on some of our systems, not all of them- but they're all using the same version of Chrome.
See https://codesandbox.io/s/8yvw057ov0 for an example. This is using the AutoSizer, but the problem persists even without it.
What is the expected behavior?
Scrolling to the end of the grid should see the headers aligned with the grid. A padding div should be created and appended to account for the scrollbars. The onScrollBarPresenceChange handler should be called.

I think we worked around it. Unfortunately I no longer work at the company that was having this problem, so they’ve probably replaced it with something else entirely
