Arguably that's like observing that the same feature works differently in 2+ browsers and blaming web devs for it. It's the job of the browser people to make correct, or at least consistent, platforms. While part of being a web dev unfortunately is also dealing with this you can't necessarily blame web devs when Safari breaks IndexedDB for the nth time, or when after using ES2018 features like regex lookarounds you discover that Safari still hasn't implemented them (which year are we in now, 2022?). You may also discover that mobile and desktop browsers work differently in some aspects, not everybody even has the resources to test every single thing in 3+ desktop browsers (which may require at least 1 VM already if you are not developing on macOS, which I think might even be illegal to run in a non-mac hardware, bizarrely) and 3+ mobile browsers (which may require at least one physical device or a macOS VM for the iPhone, and another physical device or another VM for Android, and all these VMs aren't exactly lightweight). Besides an Electron app doesn't necessarily have to run anywhere else, there's no point in checking compatibility with Gecko when your app never has to run there.
