Tooltips that have a `fixed` location now have a horizontal layout, don't render the triangles, and have a `minWidth` of the screen size with 8px of padding on each side. Also created a `fixedTooltipHeight` variable since the tooltip height for fixed tooltips will always be the same, and using inspector found out that the height of the new tooltip is 53px.
