Weird behavior in Chrome with HTML select

I have a CSS menu pretty simple, that's show an list UL on hover. From a time ago, in Chrome, when I select an option that is on the same position as the menu that's hidden by display: none, I get the menu hovered.

How a select option can hover a hidden object on click? This only happens on Chrome.

I tried to change select z-index to a higher. Changed z-index for menu to -1 until parent ul get hovered, but no success, still get the issue

Here is a code

Try select the option test5:

ul.menu ul {
    display: none !important;
}

ul.menu li:hover>ul {
    display: block !important;
}

ul.menu ul {
    position: absolute;
    left: -1px;
    top: 98%;
}

ul.menu ul ul {
    position: absolute;
    left: 98%;
    top: -2px;
}

ul.menu, ul.menu ul {
    margin: 0;
    list-style: none;
    padding: 2px;
}

ul.menu li ul.links {
    margin: 0;
    list-style: none;
    padding: 0;
    border-color: #AAAAAA;
    border-width: 1px;
    border-style: solid;
}

ul.menu ul.links li {
    margin: 0px;
    list-style: none;
    padding: 2px;

It appears to be a bug in Chrome only, I could not replicate in FF.

Try adding these 2 lines they worked when I tried them out in your Fiddle.

ul.menu li {pointer-events: none;}
ul.menu:hover li {pointer-events: auto;}
