Hi,

Here is a test case: the dropdown has a custom appearance and inherits text-rendering: optimizeLegibility from the body.
Click it to crash the page.

<!doctype html>
<html>
        <head>
                <style>
                        body
                        {
                                text-rendering: optimizeLegibility;
                        }

                        select
                        {
                                border: 1px solid red;
                                height: 32px;
                                width: 200px;
                                -webkit-appearance: none;
                                /* text-rendering: auto; uncomment and it's fine */
                        }
                </style>
        </head>
        <body>
                <select>
                        <option>click</option>
                        <option>click</option>
                </select>
        </body>
</html>
