A RichTextArea that renders links with the hand cursor.

The incubator control gives every segment's Text node the default text (I-beam) cursor, so a link would otherwise be indistinguishable from ordinary selectable text on hover — unlike org.jabref.htmltonode.FxRenderer, whose link runs carry javafx.scene.Cursor#HAND. The control has no built-in notion of links; the recommended way to react to a custom character attribute is to extend its StyleHandlerRegistry (see the incubator docs). This subclass adds a segment handler for RichTextRenderer#HREF that appends an -fx-cursor: hand inline style via the CellContext, exactly as the control's own attribute handlers do. Routing it through the cell context (rather than setting the cursor on the node directly) means the skin re-applies it on every layout and, because it replaces a segment node's whole inline style, a recycled node reused for a non-link run does not keep a stale hand cursor.
