Subject: [PATCH] Only show one tippy at a time (#24648)

Because our tippy instances have an `interactiveBorder`, it's possible
to bring up two instances at once, which is undesirable.

Prevent this by keeping track of visible tippy instances and hiding
others when one is shown. Tippy also has the [singleton
addon](https://atomiks.github.io/tippyjs/v6/addons/#singleton) for the
same purpose, but it's unsuitable to us because we don't init all
tooltips at once.
