 * The error hint only shows up with **WordPress 5.4.2**.
 * I believe that the row block has all the functions that it should have.
 * But as you can see, the output of a row block is not a valid piece of `html`,
   so I think there must be something wrong with the `save`(output) method.

 * I was using 1.1.2. When I upgrade to 1.2, there is a breaking change. `block-
   column`(1.1.2) –> `block-columns`(1.2)
 * **v1.2 still has this issue.**
 * I have checked the js code and I guess the following line is not good.
 * `return wp.element.createElement("div",{class:"row "+e.attributes....`
 * `class` may not be a proper attribute. I think the following should work:
 * `return wp.element.createElement("div",{className:"row "+e.attributes....`
