使用CSS3过渡的溢出问题

Question

I'm trying to do a small animation visible on the JsFiddle below.

But as you can see the border radius not work during the animation...

There is a fix for that?

Here is my code:

a {
    border-radius: 10px;
    display: inline-block;
    height: 300px;
    overflow: hidden;
}

a img {
    -moz-transition: all .5s ease-in-out;
    -o-transition: all .5s ease-in-out;
    -webkit-transition: all .5s ease-in-out;
    transition: all .5s ease-in-out;
    width: 100%;
    height: 100%;
}

a:hover img {
    -moz-transform: scale(1.1);
    -o-transform: scale(1.1);
    -webkit-transform: scale(1.1);
    transform: scale(1.1);
}

It is a long-standing bug in Webkit (see https://bugs.webkit.org/show_bug.cgi?id=68196 ) inherited by Chromium (see https://code.google.com/p/chromium/issues/detail?id=157218 )

A workaround is posted in How to make CSS3 rounded corners hide overflow in Chrome/Opera

You basically need to set a CSS Mask on the container element

/*1x1 pixel black png*/
-webkit-mask-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAIAAACQd1PeAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAAA5JREFUeNpiYGBgAAgwAAAEAAGbA+oJAAAAAElFTkSuQmCC);
