Apps cannot be launched from \\.\ volume paths

[Jotune]

Output of node_modules/.bin/electron --version: 6.5.0
Operating System : Windows 10 x64
Electron version: 4.0.1

Actual behaviors
I cannot start my app from a volume path. Let's say: \\.\Volume{1df47f9b-1263-11e9-8722-f46d04fd6ee0}\myapp.exe.

 fs.js:115
    throw err;
    ^

Error: EISDIR: illegal operation on a directory, lstat '\\.\Volume{1df47f9b-1263-11e9-8722-f46d04fd6ee0}\'

To Reproduce
Get the volume path of your drive using mountvol int the CMD and try to execute your electron app from it.

Additional Information

• I can run any other app from the volume path that is not electron.
• The app is bundled with electron-packager and works perfectly if started using the letter path C:\myapp.exe.
• There is a similar issue at [BUG][Win10x64] Electron will not start if the project is in a drive mapped with imdisk #7152 but I'm working with the latest node and electron.

I'm trying to understand how important this bug is, given that this surely never worked and we've never had any complaints. Why would you not just launch the app from a drive path?

[Jotune]

Hello @felixrieseberg. This matters for people using UNC path or accessing shared network folders.

[Jotune]

It works using NW.JS which uses Chromium and Node.js as well.
Electron.exe will resolve the path of the app / asar to load it. If the drive is not mapped, it can't execute the app. Changing this behavior may require a lot of work. As there is an alternative, it may not be important to fix this issue.
