	Use shallowRef instead of ref in .vue files where possible (#34813)
				
					
				
			This PR improves some `.vue` components by using `shallowRef instead of ref`, which `should improve performance`. It's probably not significant, but it's an improvement because Vue no longer deep watches the ref (shallowRef). Also i used `useTemplateRef` instead of `ref`. --------- Signed-off-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
