Motivation

Many people who use libraries not only use help of jsdoc for methods, but also for the parameters. So, moving the jsdoc declaration from before class to before constructor would definitely help many beginners using this library. Then, the descriptions would show up for the parameters as well.

Possible workarounds

The possible workaround is that instead of moving the jsdoc completely to before constructor, the description can stay before class but the @param needs to be moved to before constructor

Additional information

You don't need to use tags such as @class and @constructor with ES 2015 classes—JSDoc automatically identifies classes and their constructors simply by parsing your code.
