User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160905130425

Steps to reproduce:

Create a <select disabled="disabled"> element with options within it.

        <select disabled="disabled">
            <option value="Option 1">Disabled Select element</option>
            <option value="Option 2">Option 2</option>
        </select>

With CSS apply border-radius:0; to the Select element.

<style>
select { border-radius: 0; }
</style>




Actual results:

In Windows High Contrast Mode black theme the Select element gets a white background when border-radius:0; is applied. This makes it difficult to see the bright colored text on the white. 


Expected results:

The background color of the select element should remain black even if border-radius:0;.

This is a layout bug. It's a duplicate of 825578, which applies to <input> as well as <select>.
