Comment:

 In [changeset:"32751"]:
 {{{
 #!CommitTicketReference repository="" revision="32751"
 In `wp_ajax_hidden_columns()`, don't `explode()` on an empty string.
 In `columns.hidden()`, which lives in `common.js`, don't return items with
 no `id`.

 This was resulting in options like `manageedit-postcolumnshidden`
 containing a serialized array with random empty items.

 Props afercia, wonderboymusic.
 Fixes #32466.
