- * CKEditor's autoformatting feature (basically find and replace) has two opinionated default modes:
- * block autoformatting, which replaces the entire line, and inline autoformatting,
- * which expects a section to be formatted (but, importantly, not removed) surrounded by
- * a pair of delimters which get removed.
- *
- * Neither of those are ideal for this case. We want to replace the matched text with a new element,
- * without deleting the entire line.
- *
- * However, inlineAutoformatEditing allows for passing in a custom callback to handle
- * regex matching, which also allows us to specify which sections to remove and
- * which sections pass on to the formatting callback. This method removes the entire
- * matched text, while passing the range of the numeric text on to the formatting callback.
- *
- * If 0 or more than 1 match is found, it returns empty ranges for both format and remove, which is a no-op.
