HTML & CSS - Hover state maintained after transition

Simple example for StackOverflow

HTML

<div id="container">
    <div id="content">Hover me !
        <div class="tooltip">This is a tooltip</div>
    </div>
</div>

CSS

/** The problem **/
.tooltip {
    background-color: white;
    border: 1px solid black;
    padding: 10px;
    opacity: 0;
    transition: 1s 500ms;
    transition-property: transform, opacity;
    position: absolute;
    right: 0;
    top: 0;
}

#content:hover .tooltip {
    display: block;
    opacity: 1;
    transform:translateX(100px);
    -webkit-transform: translateX(100px);
}
#content {
    transition: 1s 500ms;
    transition-property: background-color, color;
    cursor: pointer;
    position: relative;
}
#content.active {
    background-color: blue;
    color: white;
}
#content.active .tooltip {
    opacity: 0;
    transform: none;
    -webkit-transform: none;
}

/** Just for fun **/
 html, body {
    height: 100%;
    overflow: hidden;
}
#container {
