fix(ux): update the search focus for emojis, emoticons, and gifs

• update the search focus for emojis, emoticons, and gifs to improve user experience and accessibility

Previously, when switching tabs with a hotkey, the focus was lost from the input element, on the desktop this led to suffering. Also, when submitting, the focus did not switch to the first found element and when pressing the down arrow key. This fix solves this problem for all tabs.
