See the screenshot 
* Gecko Firefox left 
* WebKit Safari center
* Blink Opera right

This is a spin off the webcompat issue

I created a minimal test case on

select {
appearance: none;
-webkit-appearance: none;}
.min-height {min-height:50px;}

<select class="min-height">
  <option value="-1">Sélectionner</option>
  <option value="8" selected="">46</option>

Expected: The text is vertically centered.
Actual: the text is align to the top.

This is happening only with min-height, when height is specified the alignment is vertically centered.
I'm not sure it's in Mats area for widget and moz-appearance.

This is happening both on Desktop and Android.
Attached file Testcase
I don't think this is related to 'appearance:none', the same issue also
occurs with native themeing.  I don't think this has ever worked correctly.

The first version that we vertically center the text in the 'height' case
is Firefox 31, before that we aligned both cases at the top.  We've never
centered the text for the 'min-height' case, AFAICT.
Flags: needinfo?(mats)
Not sure this is a similar case but we have a different alignment than WebKit and Blink. A combination of padding and height.

Attached file testcase 2

Just ran into this with Itiel when looking at a select in some Firefox frontend code, which happened to be deriving its height from min-height and had its contents misaligned as a result of this bug.

Here's a reduced testcase that I came up with while investigating.

The first "Select" text is top-aligned within the select dropdown-button.

That text should be vertically centered within its button, like all the other text.
