Flexbox not working in buttons in Firefox

Question

Apparently Firefox doesn't like display: flex on buttons. Is there a way to t correct this?

CSS:

button {
    width: 100%;
    display: -webkit-box;
    display: -webkit-flex;
    display: -moz-box;
    display: -ms-flexbox;
    display: flex;
}

    button div:first-child {
        -webkit-box-ordinal-group: 2;
        -webkit-order: 2;
        -moz-box-ordinal-group: 2;
        -ms-flex-order: 2;
        order: 2;
    }

    button div:last-child {
        -webkit-box-ordinal-group: 1;
        -webkit-order: 1;
        -moz-box-ordinal-group: 1;
        -ms-flex-order: 1;
        order: 1;
    }

HTML:

<button>
    <div>
        <p>First</p>
    </div>
    <div>
        <p>Second</p>
    </div>
</button>

tl;dr: Just put a div inside of your <button>, and make that div display:flex.

See https://bugzilla.mozilla.org/show_bug.cgi?id=984869#c2 for why display doesn't do what you expect on <button> in Firefox (and for similar things that don't work in Firefox or Webkit/Blink, for similar reasons).
