Iframe-resizer: Iframe repositioning on phpBB viewtopic

[axew3]

Hi all, sorry for but i've search around to fix this issue and starting to do some strange js things to fix it but without success until now, so i will follow with some CSS "experiment" to check another way. I know it's complex to understand how all the joke here work, but i hope somebody could help.

The scenario is a phpBB forum iframed into a WordPress page.
The issue, that i can't well explain with my bad Eng, is better explained with the direct link to an example:
https://www.axew3.com/w3/forum/
you can see that phpBB body iframe is well vertical centered in this case with correct gap between the forum wrapper and the wordpress div element that contain it:

while if the passed real phpBB link contain the anchor that scroll the phpBB viewtopic.php positioning it to view the last inserted post on topic,
https://www.axew3.com/w3/forum/?forum_id=2&topic_id=857&post_id=3183#p3183
the result is this

the iframe is forced to top and the iframe isn't correctly vertically centered.
I know it's maybe also off topic here a question like this? Do not know, i try also this. Thank anybody can take a fast look giving a possible solution, i will follow also with any update (if this will be not removed!) cheers!

it seem resolved via CSS by adding this code into the _body_ selector of the file common.css (phpBB CSS default prosilver theme in this case):

position: fixed;
  top: 0%;
  left: 0%;
  width:100%;

can't believe that this solution have come out finally

the complete correct code added into overall_footer.html is this:

// fix vertical align on viewtopic.php or preview, where # anchor etc
$(window).load(function() {
var bd = document.getElementsByTagName("body");
for (var i = 0; i < bd.length; i++) { 
    var bdID = bd[i].getAttribute("id"); 
}
var elt = document.getElementById(bdID);    
elt.setAttribute("style", "position:fixed;top:0%;left:0%;width:100%;");
});

It's valid for any phpBB theme. If no any hint on how to resolve this issue via resizer js code, this question can be considered as resolved in this way? Regards
