Closes #13782 by merging it.

fixes #13430

Generates a unique id for tooltip and adds [aria-describedby] to the element
it is called on. Resolves issue #13480

- set up test
- linted the code styles
- passed the tests
- integrated feedback from @cvrebert

primarily adds a data- attribute to the tooltip (and thus, the popover)
to create a self-reference.
