+ *                      some acceptable differences like whether there is

+ *                      Otherwise, function returning an array of objects
+ *                      which have `startContainer`, `startOffset`,
+ *                      `endContainer`, `endOffset`.  This will be called
+ *                      before calling `run()` and compared with
+ *                      `getTargetRanges()` after that.
+ *          expectInputEvent:
+ *                      `true` if it should cause an `input` event.
