I gave this a spin and was able to construct this shareable url

http://core-18976-25sbe.test-1.civicrm.org:8001/civicrm/admin/search#/create/Contact?params=%7B%22version%22:4,%22select%22:%5B%22id%22,%22display_name%22,%22postal_greeting_custom%22,%22middle_name%22%5D,%22orderBy%22:%7B%22id%22:%22ASC%22%7D,%22where%22:%5B%5B%22postal_greeting_custom%22,%22IS%20NULL%22%5D%5D,%22groupBy%22:%5B%5D,%22join%22:%5B%5D,%22having%22:%5B%5D%7D

This is something that was working so fixing in the rc makes sense
