Accidentally pushed up a commit that had it at white. This is now the correct middle grey.
The default toggle track colour was essentially a transparent black. While this works on brighter themes, it didn't work on the now default dark theme. It is now set to a "middle grey" that is visible on all themes (light or dark).
