[Tooltip] when `active` prop is `undefined`, tooltip still appears

[pt8o]

Summary

When you pass a const whose value is undefined into the active prop of a <Tooltip>, the tooltip will appear even though it shouldn't.

Expected behavior

undefined is falsy so passing undefined to active should lead to the tooltip not showing.

Actual behavior

Tooltip shows up a const with value undefined is passed into its active prop.

Steps to reproduce

Link to sandbox

1. Hover on the text to show the tooltip

Closing this because I suspect it's intended 🤔

Seems like undefined means defer to Tooltip's internal state i.e. show the tooltip on hover, hide on blur. Whereas passing in true/false is forcing the Tooltip's state from outside. I've fixed the place where I spotted this on web and will close this issue.
