 Discussed in slack with @Clorith] `.click()` should be converted to
 `.trigger('click')` except when coming from a different library. Marius
 will take a look.

 Looking in `common.js` script:

 - `.click()` [https://github.com/WordPress/wordpress-
 develop/blob/master/src/js/_enqueues/admin/common.js#L843 instance is
 here]
 - `.focus()` [https://github.com/WordPress/wordpress-
 develop/blob/master/src/js/_enqueues/admin/common.js#L1345 instance is
 here]
 - `.bind()` [https://github.com/WordPress/wordpress-
 develop/blob/master/src/js/_enqueues/admin/common.js#L1671 instance is
 here]
