So, just for posterity: this works because the channels that are defined here override the default channels that are declared by styles. And that’s specifically because styles is listed first in the spread here:

if (defaults !== undefined) channels = {...styles(this, options, defaults), ...channels};

That’s fine. It’s a little subtle, but it makes sense that the mark-specific channel definitions would override the defaults.

I’m going to rename this to “sparseTitle” instead of “titleDefined” since the interesting thing about this test is that sometimes the title is not defined. 😂
