Remove hacky patch for "safari emoji glitch fix" (#25208)

According to my test, the UI (emoji) is fine in Safari

And actually the code is just dead code, because the "resize" event is
never fired on page loading. So for most cases users just view the pages
without this hacky patch, nobody ever complains.
