<paper-tooltip>
is a label that appears on hover and focus when the user
hovers over an element with the cursor or with the keyboard. It will be centered
to an anchor element specified in the for
attribute, or, if that doesn't exist,
centered to the parent node containing it.
See: Documentation, Demo.
