[Accessibility][ComponentLibrary] Content displayed is not dismissible

[jmbuss]

Describe the bug

Standard: 1.4.13 Content on Hover or Focus (AA)
Affected Groups: Keyboard Users

Notes and Advice
Content that is displayed when a pointer hovers over the following elements is not dismissible without moving the pointer or focus (typically by pressing ESC)

Users with mobility impairments, such as hand tremors, may find it difficult to operate content when the displayed content closes too readily. Similarly, such users may unintentionally trigger the content, or may have no use for it, and need a method to dismiss it that does not require moving their current hover or focus position.

Recommendation
Ensure all displayed content keeps itself visible, which can often be done using CSS focus-within or scripting that adds hover and focus handlers to the content.

To allow content to be dismissed, adding support for the ESC key is the most common method and one that many users expect.

The tooltips for the component library should be dismissable.
