* [sql lab] fix position of 'save query' Popover
The "Save Query" popover renders on the upper left corner as opposed to
where it should (relative to the Save Query button). After a bit of
research, it seems like Popover won't render in the right place when
parents are absolute.
I'm guessing this stopped working properly when I added the resizable
panes.
Anyhow, the solution here is to use a modal instead.
