+fix: state reset issue on overlay reopen
+
+This change fixes an issue where overlays did not retain their state when reopened without unmounting, even though they were not removed from the DOM.
+The overlayReducer has been updated to maintain the state of overlays between close and open cycles, addressing an unintended state reset.
