We have a button with display:flex that contains statically positioned inline elements.
There is no absolute positioning involved, basically nothing special, and as can be seen even in the simplified fiddle, Firefox displays the children top-to-bottom instead of left-to-right.

I must be missing something almost trivial...?
Of course I could just remove display:flex and render everything inline, then it looks ok in FF for this simple case.
However, elsewhere I need to use other flex features like flex-direction so display: inline is not a viable workaround.
