Description

This allows the abbr element to retain styling if you are using tooltips.

The tooltips feature will remove the title attribute, so the original abbr[title] rule no longer applies.

Motivation & Context

Closes #39026

To allow the usage:

<abbr title="Bootstrap">BS</abbr> is awesome

and allow people to hover that text to show the full title.
