Description

Fixes #6703.

• Mouse enter/leave events are now captured on the popper and taken into account when evaluating the overall tooltip hover state.
• An optional hide delay has been added. The purpose of this is to prevent the tooltip hover state from changing when the cursor transitions from the tooltip element to the popper element (or vice versa).

These changes allow the user to interact with the tooltip popper content (e.g., clicking a hyperlink to update Signal).

This was tested on MacOS 14.2.1 (23C71) using various combinations of show/hide delay values. No new tests were written. Three new storybook examples were added for the tooltip component.
