 * Custom Sidebars plugin is causing a javascript error in the following situation:
 * When another plugin (in my case Admin Columns) is showing a notice in the plugin
   settings pages, with a ‘hide this notice’ button, the notice button cannot be
   clicked away and the page itself has the following javascript error in Console:
 * ReferenceError: wpmUi is not defined
    var modal = wpmUi._make_modal( ‘light’ );
 * or (depending on the page)
 * ReferenceError: Can’t find variable: wpmUi
 * When I disable Custom Sidebars plugin, the javascript error goes away, and clicking
   the Hide Notice button works as expected.

 * Hello rembem,
 * Thanks for reporting this. I was able to confirm that this error:
 * `Uncaught ReferenceError: wpmUi is not defined`
 * is showing in the browser console.
 * I’m letting our developer know about that issue.
 * kind regards,
    Kasia
