> Fix flaky logo spin animation restart logic

> This change updates the click handler for the Chrome logo in the help
> page to force a style recalc between removing the "spin" class and
> adding it back again. This ensures that any running animations are
> cancelled and a new animation starts.
>
> Previously the code was relying on setTimeout() to wait for a style
> recalc which was never guaranteed thus the animation would not always
> restart.
