While I would normally 100% agree with this, the &emdash; text is a pseudo-intentional bug. Changing to proper spacing makes the legibility a lot more challenging. Compare:

I appreciate the technically correct PR! That said, I've already gotten some complaints about the font and generally don't want to exacerbate the problem by making the text less legible. As such, I'm going to close this for now. Thank you for the time and effort ❤️

Besides, most of the typographic style guides I've seen do not recommend an em dash with no spaces at all.

Best practice is to surround the em dash with thin spaces — like that, or hair spaces — like that, not just a plain em dash—like that.

In any case, the full spaces here help call out the semi-deliberate error.
