Flight icon is not centered horizontally

Hi guys,

we are using material icons to rendered some tabs with rounded icons
Recently, we we noticed that flight icon (https://github.com/google/material-design-icons/blob/master/maps/svg/design/ic_flight_48px.svg) is not centered horizontally

And this is a basic example

Jsbin example

And this is a ruler guide into PS

Is it my fault? Or this could be a _bug_?

Thanks!!

Start by comparing the linked ic_flight_48px.svg with the JSBin example and the horizontal ruler shown in the screenshots. Confirm whether the icon's artwork is offset within its bounds, then ensure the flight icon is visually centered horizontally in the demonstrated tab layout.
