Wow. I always thought the argument in favor of using web technologies on the desktop was that cross-platform became easier. And yet here is an example of the most unambiguously single-platform app I can possibly imagine, and under the hood it uses web - and React of all things! Crazy.

As it turns out, React / CSS / the document-object-model are popular for more reasons than “it works on different computers.” Who knew!

I expect these additional reasons can largely be summed up as "I already know it from using it in the browser, so let's use that"

You'd probably be wrong!
