Describe your issue If Any string value is set to "THEME" unfold config variable, list pages with filter modals are flickering. You can clearly see a black flick and modal being visible before page fully loads.

If THEME does not specified, work's fine.

Problem exists on chrome but not on firefox. My chrome is not a latest, but I think it's not old (127 released on July 17 2024)
