CSS Hover + Element crashing in webkit (Chrome, Safari)

Question

Hey,

Found an annoying bug today which crashed chrome and safari (so all webkit browsers?) with just CSS.

It's a hover menu, hovering over an element then displaying the next dropdown level. Works perfectly in all other browsers.

See here, top left 'rn': http://test.davebowker.com/rn-hover/

Hope someone has some thoughts, or knows a little more about webkit than I do. I'm sure it's css, as I've disabled all javascript, and also ran the dropdown in a fresh page all on its own. I also know it's the hover + display:block that is causing it. - Just not sure how to fix it. Maybe someone else has run into this bug?

Cheers, Dave

Answer 1

Change

.ukn-network-jumper strong:hover + ul,
.ukn-network-jumper ul:hover {
    display:block;
}

to

.ukn-network-jumper strong:hover + ul,
.ukn-network-jumper:hover ul {
    display:block;
}

You don't want to display the ul when you are hovering the ul but when you are hovering the parent div.
