When a user zooms in (`ctrl/cmd` + `+`), the Vomnibar frame will extend
down past the viewport. The height is set to calc(100% - 70px) on the
actual iframe, and we can't reach it with this CSS. Setting a max-height
that is effectively the same, but measured in viewport units, on the
Vomnibar container keeps it from going past the bottom of the viewport.
* Increase input size, removing margin around search bar
* Remove top and bottom margin on unordered list used for search items
* Maintain consistent border radius by clipping child content with
`overflow: hidden`
