[v4] form-control: Remove background-image: none;

[mariusa]

form-control has
background-image: none;

Why is that?

On some sites there are customizations on select, which set webkit-appearance to none and add a background-image with an arrow.
Applying bootstrap removes that image, but also doesn't reset webkit-appearance (remains none), so select controls don't have a dropdown icon at all.

Would you please consider removing
background-image: none;
?

It's to reset unusual Firefox-on-Android default style see :
https://github.com/twbs/bootstrap/blob/v4-dev/scss/_forms.scss#L16 and
necolas/normalize.css#214

I'm wondering if adding this detail to the documentation Form controls to make sure the twbs users are aware of this detail is a good idea.

The issue has been resolved in Firefox 35 (released January 2015) according to necolas/normalize.css#214 (comment).
