The same way that I believe the web version of MS Teams to be superior to the (what is really just an Electron web app) Mac desktop version: I'm assuming the web version that will later be turned into a desktop app has to work. How is it going to work as a desktop app if it doesn't work in the native container it was designed to work in? Then throw it at Electron, and profit???

Having never written a web-based desktop app in my life, this is all out of my butt. But at some point I think it reasonable that there are assumptions once the web app is working that don't cleanly port to Electron or summat, and no one cared to check or cared to fix it.
