Cutting mask for SVG

Question

I am trying to create a menu that, when you hover over one of the links, displays a sliced ​​image in the background. I was able to create something that only works in Chrome using CSS3 clipping masks.

The code for creating these forms with a browser width (+1 for percent!) Works just fine, except for two things: one of them is that the mask does not crop the shape I need (refer to the color image to see the shape ), and it is impractical to use with Firefox and IE.

#music_hover {
    z-index: 5;
    width: 100%;
    height: 100%;
    background: red;
    -webkit-clip-path: polygon(50% 50%, 100% 50%, 100% 100%, 70% 100%);
    clip-path: polygon(50% 50%, 100% 50%, 100% 100%, 70% 100%);
    float: right;
    position: absolute;
    background: url(../music.jpg) bottom right no-repeat;
    display: none;
}
