possibly defeat losing of focus for prompt when generating images with gallery open

            let galleryBtnSelected = gradioApp().querySelector('#'+id_gallery+' .gallery-item.\\!ring-2')

            if (prevSelectedIndex !== -1 && galleryButtons.length>prevSelectedIndex && !galleryBtnSelected) {

                // automatically re-open previously selected index (if exists)

                activeElement = document.activeElement;

                activeElement = gradioApp().activeElement;

                galleryButtons[prevSelectedIndex].click();

                showGalleryImage();

                if(activeElement) activeElement.focus()

                if(activeElement){

                    // i fought this for about an hour; i don't know why the focus is lost or why this helps recover it

                    // if somenoe has a better solution please by all means

                    setTimeout(function() { activeElement.focus() }, 1);

                }

            }

        })

        galleryObservers[id_gallery].observe( gallery, { childList:true, subtree:false })
