allow-top-navigation didn't work at latest Safari Mobile,iOS10.3.1

I want to prevent an iframe replacing top window's location(url),and I use

<iframe src="./iframe.html" security="restricted" sandbox="allow-forms allow-modals allow-same-origin allow-scripts"></iframe>

and the code of iframe.html

<script>

setTimeout(function(){

top.window.location.replace('https://www.apple.com');

},1000)

</script>

It works correct on Windows 10 Chrome.FireFox and Android,successfully prevented top.window.location ,but safari mobile didn't,I must remove thi allow-scripts value ,and it disaled all scripts of iframes.

Does safari support allow-top-navigation?
