Adds HTML Abbreviation <abbr> support to VSCode's markdown preview.
Overview
The abbr plugin lets you define abbreviations once and automatically wraps every occurrence in an <abbr> element with a title attribute for the full expansion.
Define abbreviations anywhere in the document using the *[ABBR]: Full text syntax. Definitions are removed from the output and all matching words are wrapped automatically.
