Flexbox centering and overflow bug in IE10? - css

Question

What I want to do basically is have a header and a container always centered if they're small than the screen (body with 100% height). In case the content and header are bigger than the screen, then allow to scroll inside its container (notice that the header shouldn't be scrollable).
I managed to make it work in Chrome but not in IE10. This is the JSFiddle.
var p = $('p');
$('button').click(function(){
for(var i=0; i<30; i++){
$('.content').append(p.clone());
}
});
.screen{
border: 1px solid red;
padding: 3px;
height: 300px;
display: flex;
display: -ms-flexbox;
justify-content: center;
-ms-flex-pack: center;
flex-direction: column;
-ms-flex-direction: column;
}
.header{border: 1px solid blue; padding: 10px;}
.content{ border: 1px solid green; background: #aaa; overflow: auto;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>Add more content</button>
<div class="screen">
<div class="header">
Header
</div>
<div class="content">
<p>This is the content</p>
</div>
</div>

You need to add flex: 0 1 auto; to the .content div and overflow: auto; to the .screen container. IE10 uses the 2012 syntax which defaults to flex: 0 0 auto instead of the modern value of flex: 0 1 auto;
var p = $('p');
$('button').click(function () {
for (var i = 0; i < 30; i++) {
$('.content').append(p.clone());
}
});
.screen {
border: 1px solid red;
padding: 3px;
height: 300px;
display: flex;
display: -ms-flexbox;
justify-content: center;
-ms-flex-pack: center;
flex-direction: column;
-ms-flex-direction: column;
overflow: auto;
}
.header {
border: 1px solid blue;
padding: 10px;
}
.content {
border: 1px solid green;
background: #aaa;
overflow: auto !important;
flex: 0 1 auto; /* Add this property value */
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>Add more content</button>
<div class="screen">
<div class="header">Header</div>
<div class="content">
<p>This is the content</p>
</div>
</div>
