When a form becomes invalid and displays an error, the error message was no longer animating. This regression was introduced in angular#30678 (accessibility changes), because error elements were no longer destroyed/re-rendered, preventing the CSS animation from running. This fix ensures that the animation works again without impacting accessibility. Fixes angular#31712
