Firefox "radio" alignment i the time ring.

[Nutul]

Very minor cosmetic issue.
When playing a radio stream the text that says ( Radio ) instead of the track length in the time ring is not centred when using Firefox:


Chromium looks fine though:


This is on Linux Mint in case that's relevant.

I'm looking into the html now, and that appears to be an image in .svg format. I believe the font names used in the SVG are not available in Firefox, hence the wrong rendering (but why?!?!?); as I added "Times New Roman" as an alternative, it immediately centered.
(original font names were just these two: AvenirNext-DemiBold, Avenir Next)


@Tim Curtis worth investigating?
