-/**
- * TipTap is a stateful rich-text editor, which is extremely useful
- * when you _want_ it to be stateful formatting such as bold and italics.
- *
- * However we also use "stateless" behaviors, specifically for URLs
- * where the text itself drives the formatting.
- *
- * This plugin uses a regex to detect URIs and then applies
- * link decorations (a <span> with the "autolink") class. That avoids
- * adding any stateful formatting to TipTap's document model.
- *
- * We then run the URI detection again when constructing the
- * RichText object from TipTap's output and merge their features into
- * the facet-set.
