Shows a ViraTooltip with the given contents while the element that this directive is
attached to is hovered or focused, or as options.trigger describes. The tooltip is centered
above the element when it fits, otherwise it is aligned to the element's left or right edge, and
it flips below the element when there's no room above. The tooltip is inserted right after the
element, so styles from the element's shadow root apply to template contents.
