Two quick points:

• This is happening in prod, so it's not something we should block on.
• I actually can see the horizontal scroll bar if I scroll down to the bottom of the data set with the vertical scroll bar.

It's definitely awkward, though, so we should leave this open and fix it soon.

I can't reproduce this anymore, at least on macOS and Ubuntu. @madalincm Would you mind checking if this is still true?

Still reproducing for me on Win7x64 and MacOS 10.14.1 FF68 on dev stage and prod using this query:

Hm, I think we should file this upstream and ask if they could exclude the paginator from the scrollable area since right now, the reason why the horizontal scrollback doesn't show up is because when you start scrolling at the top of the result list, it affects the encasing containers, which scrolls vertically. It just happens to also contain the result list which is larger than what the container can show and correctly shows the horizontal bar below.
