This test verifies that the dropdown background colors of &lt;select&gt; and &lt;select size="0"|"1"&gt; are consistent. You should see PASS below if test passes. Otherwise, FAIL shows up.
<div id='result'>Oops</div>

Default:
<select id='default-select'>
    <option>Item 1</option>
    <option>Item 2</option>
</select>

Size=0:
<select size="0" id='size0-select'>
    <option>Item 1</option>
    <option>Item 2</option>
</select>

Size=1:
<select size="1" id='size1-select'>
    <option>Item 1</option>
    <option>Item 2</option>
</select>

<br>
Note: Two items are used so that you could manually see the difference. The test logic only needs the first item to run.
