+ * "normal style" having been set to the el.

+ * a default hover style).
+ *
+ * The reason: this method treat the current style of the `el` as the "normal style"
+ * and cache them when enter/update the "emphasis style". Consider the case: the `el`
+ * is in "emphasis" state and `setOption`/`dispatchAction` trigger the style updating
+ * logic, where the el should shift from the original emphasis style to the new
+ * "emphasis style" and should be able to "downplay" back to the new "normal style".
+ *
+ * Indeed, it is error-prone to make a interface has so many constraints, but I have
+ * not found a better solution yet to fit the backward compatibility, performance and
+ * the current programming style.
+ *
+ * (2)
+ * Call the method for a "root" element once. Do not call it for each descendants.
