Fixed headers with text fields on mobile safari websites

I've been looking around for awhile, and I can't seem to find any fix for this issue. When an input field gains focus in mobile safari (haven't checked other browsers) a fixed element will jump due to safari putting that element in view (closer to the center). The error only occurs when a user has scrolled, if the user is still at the top of the page nothing occurs.

Does anyone have a clue how to fix this? The only solution I have come across is to scroll back to the top when focused, then on blur scroll back into position... this seems like a very sloppy solution.

Here's the example site in the screenshots, very basic, nothing out of the norm.

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8" />
        <meta name="viewport" content="width=device-width, scale=1"/> 
    <title>MySite</title>
    <style>
    body{
        height:100%;
        width:100%;
        padding:0;
        margin:0;
        font-size:16px;
        font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
    }
    header, footer {
        background-color:#333;
        padding:10px;
        color:#FFF;
        width:100%;
    }
    header {
        position:fixed;
        top:0;
        left:0;

    }
    input[type=search] {
        position:relative;
        margin-left:20px;
        width:160px;
        font-size:16px;
        height:26px;
    }
    section{
        padding:10px;
    }
    </style>
</head>
<body>
<header>
<b>MySite</b>
<input type='search' placeholder='Search'>
</header>
<section>

I have the same issue. But I realized that the fixed position is just delayed and not broken (at least for me). Scroll and wait 5-10 seconds and see if the search bar adjusts back to the top of the screen. I believe it's not an error but a delayed response when the keyboard is open.
