Comment (by rachelbaker):

 While testing a patch for #35501, I found I kept getting the following
 error in my console log:
 > wp-lists.js?ver=4.6-beta2-37993-src:310 Uncaught TypeError: Cannot read
 property '0' of undefined

 which was happening because line 300 of wp-lists.js has this conditional:
 {{{#!js
 if ( 'undefined' !== typeof res.responses[0].supplemental.comment_link ) {
 }}}

 where somehow I was able to trigger a condition where `res = true`.

 We should, at least, check that `res.responses` isn't `'undefined'` in the
 same conditional.

 Something like this:

 {{{#!js
 if ( 'undefined' !== typeof res.responses && 'undefined' !== typeof
 res.responses[0].supplemental.comment_link ) {
 }}}
