`dotnet format` expects me to put a space between the spread `..` and
the expression after which is UTTERLY STUPID AND UGLY AND WRONG AND
CANNOT BE `.editorconfig`'d BECAUSE [INSERT EXCESSIVELY LONG BLEEP].
God I hate when good features are kneecapped by this sort of stupidity.
The test scene doesn't exercise the custom sample playback, but I hope I
can be forgiven for this as setting up a custom editor beatmap just for
this to work is rather cumbersome.
