Steps to reproduce:

When an element has a font-size of 0, any children elements inside it which have font-size set to inherit will not be scrollable via the mousewheel.

Here is a test case: http://jsfiddle.net/PqYpd/

If JsFiddle doesn't work, here is the code to reproduce the issue:

<span style="font-size:0">
    <ul style="height:80px;overflow:auto;">
        <li>One</li>
        <li>Two</li>
        <li>Three</li>
        <li>Four</li>
        <li>Five</li>
        <li>Six</li>
        <li>Seven</li>
        <li>Eight</li>
        <li>Nine</li>
        <li>Ten</li>
    </ul>
</span>


Actual results:

Mousewheel did not scroll the <ul> container.


Expected results:

Mousewheel should scroll the <ul> container.
