This is the case we looked at when we originally replaced the
customize widgets with SVGs. At the time we very intentionally removed
the colour and size information from the SVG files (checkbox.svg, etc)
so that they would match the colours and font size of the surrounding
text.

I guess, unfortunately, these arrows were missed.
