Let me rephrase this in a way which is more interesting for the Web
compatibility stand point of view.
SHIP: OK!
-appearance: none
-webkit-appearance: none
UNSHIP: OK with a condition.
-moz-appearance: none
If I check carefully the way the site are currently dropping the arrows on the
select/option widget is by having -webkit-appearance: button or
-webkit-appearance: none.
For compatibility we would need this at the same time we unship
-moz-appearance: none
-webkit-appearance: button
-moz-appearance: button
appearance: button
-webkit-appearance: button and -moz-appearance: button behaves differently.
See the bug https://bugzilla.mozilla.org/show_bug.cgi?id=1246836
I created a test.
http://www.la-grange.net/2017/02/21/appearance/appearance-test-0001.html
The issue is that when we set
-moz-appearance: button
we get a widget with arrows while -webkit-appearance: button deliver a simple
button.
So if the site does:
-webkit-appearance: button;
-moz-appearance: button;
background: <image>
The rendering looks broken in Firefox.
and if the site does:
-webkit-appearance: button;
-moz-appearance: none;
appearance: button
background: <image>
the site will be broken if we unship -moz-appearance: none
